Question

What is the volume of the figure

Answer 1

To find the volume, break the figure into 2 parts, the longer rectangle across the bottom and then the smaller square on top.

volume = L x W x H

the lower rectangle has L=20, W =5 and H = 5
 Volume = 20 * 5 * 5 = 500 cubic inches
 the top square has L = 5, W = 5 and H = 5
volume =  5*5*5 = 125 cubic inches
 total volume =  500+125 = 625 cubic inches
