The brand of sand chosen by Alisa is Sand A with a total cost of <u>$10,816</u>, instead of Sand B with a total cost of <u>$11,267.</u>
<h3>How are the total costs determined?</h3>
The total costs are determined using mathematical operations and unit conversions.
Firstly, the volume of the court is calculated, using V = l x w x h. The result is converted from cubic feet to pounds at <u>1 ft³ = 100 lb</u>.
After the conversion, the rest of the calculations carried on the mathematical operations of addition, division, and multiplication.
<h3>Data and Calculations:</h3>
The length of the volleyball court = 52 feet
The width of the volleyball court = 26 feet
The height of the volleyball court = 1 feet
The volume, V = l x w x h
= 52 x 26 x 1
= 1,352 feet³
1 ft³ = 100 lb
1,352 feet³ = 135,200 lb (1,352 feet³ x 100)
Sand A's Cost = $12 per 150 lb
135,200 lb = <u>$10,816</u> ($12 x 135,200/150)
Sand B's Cost = $5 per 60 lb
135,200 lb = <u>$11,267 </u>($5 x 135,200/60)
Thus, Sand A, most likely chosen by Alisa, is more cost-effective than Sand B.

<h3>Question Completion:</h3>
Alisa hopes to play beach volleyball in the Olympics someday. She has convinced her parents to allow her to set up a beach volleyball court in their backyard. 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 = 150Ibs = $12
Sand B = 60lbs = $5
