Vprism= ( 48 )( 48 )( 18 ) = 41472 cm^3
Vpyramid=

( 482 )( 7 ) = 5376 cm^3
The total volume is 41472+ 5376 = 46 , 848 cm^3.
- Use what you know about prisms.
Vprism=B·h
Vprism= ( 4 · 4 )· 5
Vprism= 80 in^3
- Use what you know about pyramids.
Vpyramid=

B·h
Vpyramid=

( 4 · 4 )( 6 )
Vpyramid= 32 in^3
Now find the total volume by finding the sum of the volumes of each solid.
Vtotal=Vprism+Vpyramid
Vtotal= 112 in^3
