you need some more information. Maybe mass, temperature and pressure, then tou can use the ideal gas law to find volume. PV = nRT
You from calculate how TV gas how and Volume RR
density = mass/volume
w x h
density = mass/volume
The volume is pi*r^2*h where r is the radius of the circular] cross section and h is the height (or length).
1/2 h(a+b)
It is not. The density and mass would be used to find the volume.
Use Boyle's law
V=nRT/P
Volume = {pi}r2h where r = radius of base, h = height of cylinder.
its just the volume which is l•w•h (lengthxwidthxhight
calculate the overall volume as if the prism wasn't truncated and did form a central peak (v = 1/2*b*h*l), then calculate the volume of the prism above the truncation. Then deduct this from the overall volume.
