What is the volume of this rectangular prism in cubic feet?

Height: 2 yd

Width: 9 ft

Length: 3 yd

Answers:

A: 486 ft

B: 54 ft

C: 18 ft

D: 9 ft

Question asks for answer in units of cubic feet so all dimensions must be converted from yards to feet.

ft x ft x ft = ft^3

Look up conversion: 1 yard = 3 ft

height = 2 yd * 3 = 6 ft

width = 9 ft

length = 3 yd * 3 = 9 ft

volume = 6 ft x 9 ft x 9 ft = 486 ft^3
