Answer:

D. 1,164 cubic yards

Step-by-step explanation:

Volume of a rectangular prism is width times length times height.

V = WLH

The volume of the top prism is:

V = (3 yd) (9 yd) (4 yd)

V = 108 yd³

The volume of the bottom prism is:

V = (6 yd) (22 yd) (8 yd)

V = 1056 yd³

The total volume is 108 yd³ + 1056 yd³ = 1164 yd³.
