Explanation:
First, split the figure into two different rectangular prisms. I found it easiest to split it like this (image attached below).
To find the volume of the lower prism, multiply the Length (6ft) x Width (2ft) x Height (3ft).
6 * 2 * 3 = 36

Next, subtract 3 from 8 to get the height of the top prism. 8 - 3 = 5, so the height of the top prism is 5.
Multiply the Length (4ft) x Width (2ft) x Height (5ft).
4 * 2 * 5 = 40 ft

Add the two volumes.
40 + 36 = 76 ft^3.
