Question

N the construction of a new building, a landscape architect determined that he had a plot 810 feet by 35 feet, to be filled to a depth of 6 inches with loam. how many cubic yards of loam would he require?

Answer 1

Volume is the product of length, width, and depth. Since you want the result in cubic yards, it is convenient to convert the measures to yards.
  (270 yd)*(35/3 yd)*(1/6 yd) = 525 yd³ . . . . required volume of loam
