Question 100985: the riches are ording topsoil for teir new lawn. The topsoil will be spread evenly over the yard before the grass is planted. the yard is 81 feet wide and 111 feet long. the topsoil will be spread 2 inches deep. how many cubic yards of topsoil are needed.
You can put this solution on YOUR website! Ok for this problem we have to imagine a box that is
81 feet wide
111 feet long
and has a height of 2 inches
Next the problem gives measurements in feet and inches. We need to express all the measurements given in the same units. Lets convert all units to inches.
Since 1 foot equals 12 inches all we have to do is multiply number of feet times 12. so...
81ft times 12in = 972 inches
and
111ft times 12in = 1332 inches
Ok so now we are looking at a rectangle box that is
972 inches wide
1332 inches long
and has a height of 2 inches
So now we can use the formula for Volume of a rectangle box to find out how much topsoil the riches need.
Volume = length * width * height
So lets plug in the values we know
Volume = (972)(1332)(2)
Volume =
This is the volume in inches, but the questions asked for cubic yards. So we need to convert inches into yards. There are 36 inches in a yard. So we need to divide 2589408 by 36 to find cubic yards.
2589408/36 = 71928
