Question

A window box shaped like a rectangular prism has a length of 12 feet, a width of 9 feet, and a height of 9 feet. If one bag contains 2 cubic feet of soil, how many bags of soil must you buy to fill the window box? If each bag of soil costs $4.97, what is the cost of filling the window box? (show work)

Answer 1

Number of bags required = 486

Total cost to fill the window box = $2415.42.

Explanation:

Volume of the rectangular prism = l × b × h

= 12 × 9 × 9 cubic feet

Volume of 1 bag of soil = 2 cubic feet

Number of bags required =
`(12(9)(9))/(2)`

= 486

Cost of one bag = $4.97

Cost of 486 bags = 486 × 4.97 = 2415.42

Hence, total cost of filling the window box = 2415.42.
