volume of a square based pyramid is V = 1/3 b^2 h

Volume of a square prism is V = b^2h

just add the two volumes together.

anonymous · Answer

V=1/3*16^2*12
V=1/3*256*12
v=1/3*3072
v=1024
and 
V=b^2*h
V=16^2*3
V=256*3
V=768
 Total volume = 768+1024
Total Volume = 1792?

b = the length of a side of your base

anonymous · Answer

okay so V=64
V=48
Total volume =112
