Answer 1

15

Explanation:

the formula of finding the volume of a rectangular prism is base times height. the base dimensions are 20*30 so its 600 square inches, 9000/600=15.

Answer 2

15 in.

Explanation:

Volume of rectangular prism = length × width × height

Length = 30 in

Width = 20 in

Height = x

Volume of rectangular prism = 9000 in³

Volume of rectangular prism = length × width × height

9000 = 30 × 20 × x

9000 = 600x

x = 9000/600

x = 15 in
