Volume of a rectangular prism: l × w × h
Split the prism into two rectangular prisms.
We have a rectangular prism with side lengths of 8 by 7 by 5.
The other prism has side lengths of 8 by 3 by 8.
Plug these numbers into the formula:
8 × 7 × 5 = 280
8 × 3 × 8 = 192
Now add up both volumes of the prisms to find the volume of the entire rectangular prism.
280 + 192 = 472
The volume of the figure is 472 yards³.
