Question

You need to cover the playground of a child development center with mulch. The playground is 125 feet long and 60 feet wide. You want the mulch to be at least 6 inches deep. How many cubic yards of mulch should you have delivered? Round your answer to the nearest whole number.

Answer 1

Change 125 and 60 into inches 
1500 and 720
1500*720=1,080,000 (area)
multiply by 6
1,080,000*6=6,480,000
divide by 12 to make it into feet
6,480,000/12=540,000
divide by 3 to make it into yards
you need 180000 cubic feet of mulch
