Question

You must buy bags of cement to pour a cement pad for a hot tub. You need to fill the pad frame which is a square frame measuring 8 feet long and 1 foot high. Each bag of cement will fill 5 cubic feet. How many bags will you need to buy to ensure enough to fill the entire frame?

please show all steps

Answer 1

13

Explanation:

volume of pad : 8x8x1=64

64/5=12.8

so you would need 13 bags

Answer 2

Explanation:

Since the pad frame is a square frame measuring 8 feet long and 1 foot high, we would determine its volume by applying the formula for determining the area of a cuboid which is expressed as

Volume = length × width × height

Volume of pad frame = 8 × 8 × 1 = 64 cubic feet

Since each bag of cement will fill 5 cubic feet, then the number of bags that you will need to buy to ensure enough to fill the entire frame is

64/5 = 16.8

Approximately 17 bags
