Question

Colin Is buying dirt to fill a garden bed that is a 9ft by 11ft retangle. If he wants to fill to a depth of 4in. How many cubic yards of diets does he need? If necessary, round to the nearest cubic yard.

Answer 1

1584 yards cubed.

Convert all the measurements to inches.
9*12=108
11*12=132
Multiply 108 and 132 to get the area.
108*132=14256
Multiply 14256 by 4 to get the volume.
14256*4=57024
Divide by 36, because there are 36 inches in a yard.
57024/36= 1584 Yards Cubed
