Question

A standard beach volleyball court is approximately 26 feet by 52 feet. She figures that she will need the sand to be one foot deep. She goes to the hardware store to shop for sand and sees the following signs on pallets containing bags of sand. Sand A is 60 lbs for $5 and Sand B is 150 lbs for $12. She uses her cell phone to search how many pounds of sand is required to fill 1 cubic foot and finds the answer is 100 pounds. Use brand A and compute how much it will cost Alisa to purchase enough sand to fill the court.

Answer 1

Volume of a rectangular prism:

V = lwh

V = (52)(26)(1)

V = 1352 cubic feet

1 cubic foot = 100 pounds

100 * 1352 = 135,200

Sand A = 60 pounds for $5

135,200 / 60 = 2253.33

2253.33 * 5 = $11,266.65
