Q:
# Find the volume of the composite solid.A. 420 ft^3B. 530 ft^3C. 630 ft^3D. 840 ft^3

Accepted Solution

A:

THe bottom rectangular prism has volume 8*7.5*7 = 420 cu ft

The top triangular prism has a volume of 1/2 * 7 * 7.5 * 8 = 210 cu ft

Total volume = 420+210 = 630 cu ft

The top triangular prism has a volume of 1/2 * 7 * 7.5 * 8 = 210 cu ft

Total volume = 420+210 = 630 cu ft
