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

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
