Ratio is made of 8+5+7=20 parts.

900=%288%2F20%29%2Af%5D%5D%5D%2C++some+factor+f.%0D%0A%7B%7B%7B900=%284%2F5%29%2Af
f=900%2A5%2F4
f=1125

Width is %285%2F20%29%2A1125=%281%2F4%29%2A1125=highlight%28281.25%29

Height is %287%2F20%29%2A1125=highlight%28393.75%29

Volume is %28900%29%2A%28281.25%29%2A%28393.75%29%2Acm%5E3.
