Real-Life Math -- Solution
You're ordering limestone screening to go under rubber tiles on a playground. This is how you figure out how much you will need to order:
If the playground is 10 yards by 20 yards, and the limestone screening needs to be half an inch thick, how many cubic yards of limestone screening will you need to purchase?
Playground is 10 yards by 20 yards
Width = 10 yards
Length = 20 yards
Limestone screening needs to be 0.5 inches thick
0.5 inches = 0.013 yards
Height = 0.013 yards
Volume = length x width x height
Volume = 10 yards x 20 yards x 0.013 yards
Volume = 200 x 0.013
Volume = 2.6 cubic yards
You will need 2.6 cubic yards of limestone screening.
If the screening costs $300 per cubic yard, how much money will you need?
2.6 cubic yards x $300 = $780
The load will cost you $780.
