Question

Claire wants to buy enough sand to fill a sandbox that is shaped like a rectangular prism. The sandbox is 4 feet long, 4 feet wide, and 0.5 foot high. If a bag of sand holds 0.5 cubic feet and costs $2.55 per bag, how much will it cost her to fill the sandbox?

Answer 1

First, find the volume of the sand box
4 x 4 x 0.5 (L x W x H) = 8

8 divided by 0.5 is 16, so you need 16 bags
Well,how much does that cost

16 x 2.55 = $40.80

Hope this helps :D
