Strelizia Apus is one absolutely colossal mecha, and given there are a few calcs I have in mind for it, I'll scale it's size and mass here. Nisigoori has said Strelizia True Apus is around 10km tall, but given her size next to the 3km Plantations, that size seems way off. Machine scaling is never easy, and in the case of Strelizia Apus & True Apus this is very much so. Strelizia Apus was formed from Star Entity, which we can scale from Plantation 13. Plantations have a height of 1200m.
Star Entity's crushes Plantation 13 between its index and middle finger.
181 pixels = 1200m
1 pixel = 1200m/181 = 6.62983425m
6.62983425m X 358 = 2373.48066m
That's the easy part done, now to scale the dimensions of Strelizia Apus, starting with all the pointy armour...
6 pixels = 2373.48066m
1 pixel = 2373.48066m/6 = 395.58011m
395.58011m X 74 = 29272.9281m
395.58011m X 126 = 49843.0939m
395.58011m X 135 = 53403.3148m
395.58011m X 91 = 35997.79m
35997.79m/2 = 17998.895m
395.58011m X 147 = 58150.2762m
395.58011m X 70 =
58150.2762m + 27690.6077m = 85840.8839m
395.58011m X 9 = 3560.22099m
395.58011m X 154 = 60919.3369m
395.58011m X 119 = 47074.0331m
395.58011m X 371 = 146760.221m
395.58011m X 207 = 81885.0828m
81885.0828m/2 = 40942.5414m
395.58011m X 667 = 263851.933m
395.58011m X 102 = 40349.1712m
395.58011m X 117 = 46282.8729m
46282.8729m/2 = 23141.4365m
395.58011m X 201 = 79511.6021m
395.58011m X 74 = 29272.9281m
29272.9281m/2 = 14636.4641m
395.58011m X 130 = 51425.4143m
51425.4143m/2 = 25712.7071m
395.58011m X 198 = 78324.8618m
395.58011m X 169 = 66853.0386m
66853.0386m/2 = 33426.5193m
395.58011m X 352 = 139244.199m
Shall we begin? Volume of her knee protectors and leg protectors as triangles added together.
A = hbb/2
= 29272.9281 X 49843.0939/2
= 729526652m^2
Then we times that by the depth to get the volume, and times it by two for both knees.
V = 729526652 X 3560.22099
= 2.5972761e12 X 2
= 5.1945522e12m^3
A = hbb/2
= 29272.9281m^2
V = 29272.9281 X 53403.3148/2
= 781635697 X 3560.22099
= 2.78279581e12 X 2
= 5.56559162e12m^3
Next, for the interior parts, as two pyramids, with the above volumes subtracted.
V = 1/3AH
= 1/3 X 729526652 X 29272.9281
= 7.11846041e12 X 2
= 1.42369208e13 - 5.1945522e12
= 9.0423686e12m^3
V = 1/3AH
= 1/3 X 781635697 X 29272.9281
= 7.62692185e12 X 2
= 1.52538437e13 - 5.56559162e12
= 9.68825208e12m^3
V = 9.0423686e12 + 9.68825208e12
= 1.87306207e13m^3
In order to get the surface area of a cone I entered the values (17998.895m in radius and 58150.2762m high) into a calculator and got 4460000000m^2.
V = 4460000000 X 3560.22099
= 1.58785856e13 X 2
= 3.17571712e13m^3
Interior part as a cone (with the above subtracted, and again times by two for both of them).
V = πr^2h/3
= π X 17998.895^2 X 58150.2762/3
= 1.97275016e13 X 2
= 3.94550032e13 - 3.17571712e13
= 7.697832e12m^3
Volume of her leg protectors as triangles. Note of the upper two triangles she has two on each leg, which gives us a total of four.
A = hbb/2
= 60919.3369 X 47074.0331/2
= 1.43385944e9 X 4
= 5735437760m^2
V = 5735437760 X 3560.22099
= 2.04194259e13m^3
Now for the lower leg triangles.
A = hbb/2
= 146760.221 X 60919.3369
= 8.94053535e9 X 4
= 35762141400m^2
V = 35762141400 X 3560.22099
= 1.27321126e14m^3
The interior parts as triangular pyramids.
V = 1/3AH
= 1/3 X 8.94053535e9 X 60919.3369
= 1.81550495e14 X 2
= 3.6310099e14 - 1.27321126e14
= 2.35779864e14m^3
For the huge thing on the back we'll use a cone for the back end, which for the surface area we'll once again enter the values (a radius of 40942.5414m and 263851.933m long) through a calcuator, which reveals a surface area of 39600000000m^2.
V = 39600000000 X 3560.22099
= 1.40984751e14m^3
For the interior parts, we'll use a cone (subtracting the above, of course).
V = πr^2h/3
= π X 40942.5414^2 X 263851.933/3
= 4.63167942e14 - 1.40984751e14
= 3.22183191e14m^3
For the front end, we'll use a frustrated conical frustrum.
Using this calculator here, we can determine it has a total surface area of 15827400000m^2.
V = 15827400000 X 3560.22099
= 5.63490417e13m^3
Next, of course, its interior dimensions.
V = (1/3)π(r^2+rR+R^2)h
= (1/3) X π X (23141.4365^2 + 23141.4365 X 40942.5414 + 40942.5414^2) X 40349.1712
= 1.33491102e14 - 5.63490417e13
= 7.71420603e13m^3
Now for the volume of the back legs as two cylinders and a cone. First segment...
A = 2πrh + 2πr^2
= 2 X π X 14636.4641 X 79511.6021 + 2 X π X 14636.4641^2
= 8.65819662e9m^2
V = 8.65819662e9 X 3560.22099
= 3.08250933e13m^3
V = πr^2h
= π X 14636.4641^2 X 79511.6021
= 5.35121895e13 - 3.08250933e13
= 2.26870962e13m^3
Second segment...
A = 2πrh + 2πr^2
= 2 X π X 25712.7071 X 78324.8618 + 2 X π X 25712.7071^2
= 1.68080707e10m^2
V = 1.68080707e10 X 3560.22099
= 5.98404461e13m^3
V = πr^2h
= π X 25712.7071^2 X 78324.8618
= 1.62684102e14m^3
V = 1.62684102e14 - 5.98404461e13
= 1.02843656e14m^3
Third segment, as a cone. Once again using the calculator (for a radius of 33426.5193m and a length of 139244.199m) we get a surface of area 18500000000m^2.
V = 18500000000 X 3560.22099
= 6.58640883e13m^3
V = πr^2h/3
= π X 33426.5193^2 X 139244.199/3
= 1.62925117e14m^3
V = 1.62925117e14 - 6.58640883e13
= 9.70610287e13m^3
Now to add the exterior and interior parts together.
V = 3.08250933e13 + 5.98404461e13 + 6.58640883e13
= 1.56529628e14m^3
V = 2.26870962e13 + 1.02843656e14 + 9.70610287e13
= 2.22591781e14 X 2
= 4.45183562e14m^3
Last but not least, we need the values of the humanoid part of Stelitzia Apus.
315 + 195 + 329 = 839
395.58011m X 839 = 331891.712m = 331.891712km
To find the surface area of her body, we'll scale up from a female body using square-law.
Zero-Two is 170cm (or 1.7m) and
the average mass of a 16 year old girl is 53.5kg.
M2 = (H2/H1)^3*M1
= (331891.712/1.7)^3*53.5
= 3.98103724e17kg
Entering the heigh and mass
into this calculator, we get a variable number of surface areas, so let's get an average (ignoring the Biyd and Schlich formula's, as both are outliers on both end of the scale).
A = 16217846544.78 + 17874819076.91 + 18581529949.17 + 18728961353.28 + 22526536559.03 + 27694900835.94
= 1.21624594e11/8
= 15203074250m^2
V = 15203074250 X 3560.22099
= 5.41263041e13m^3
For our volume for the interior, we'll be using
this forumla...
V = m/d
V = volume
m = mass
d = density
The average density of the human body (from the above link) is 1010 kg/m^3.
V = 3.98103724e17/1010
= 3.94162103e14m^3
V = 1.43796025e15 - 5.41263041e13
= 1.38383395e15m^3
At last, we can add everything together for our mass. First for the exterior...
V = 5.1945522e12 + 5.56559162e12 + 3.17571712e13 + 2.04194259e13 + 1.27321126e14 + 1.40984751e14 + 5.63490417e13 + 4.45183562e14 + 5.41263041e13
= 886901525720000m^3
...then for the interior.
V = 1.87306207e13 + 7.697832e12 + 2.35779864e14 + 3.22183191e14 + 7.71420603e13 + 4.45183562e14 + 1.38383395e15
= 2490551080000000m^3
For our exterior armour, we'll steel,
which weighs 7850kg/m^3 (usually I go with titanium, but given the interior part below seems a lot lighter than it should I think steel is a good choice).
M = 886901525720000 X 7850
= 6.96217698e18kg
Now for the mechanical unseen interior, which is somewhat harder. The light ship mass of container vessel 2700TEU is
102.56kg/m^3 (or 0.10256g/cm^3). I've a feeling this is a colossal low end, but it's the best I've got for now, so I'll take it.
M = 2490551080000000 X 102.56
= 2.55430919e17kg
Finally, to add both together for our final mass.
M = 6.96217698e18 + 2.55430919e17
= 7.2176079e18kg
= 7217607900000000 tons
Final Results
Strelizia Apus' size = 331.892km
Strelizia Apus' mass = 7217607900000000 tons I'm not sure if the scaling is entirely accurate, but given there'd be a lot more unseen machinery (such as under the back part where we can see some engines) it would be even greater in mass, though that's the best I can do with what I've got. Strelizia True Apus would be equal in size and mass.
