Question is wrong. You need three (3) measurements, Length, width and height to get cubic feet.
100/3 ft x 100/3 ft x 15/3 ft = 150000/27 cu ft = 5555.55+ cubic feet
21 cubic feet is a measurement.21 cubic feet is a measurement.21 cubic feet is a measurement.21 cubic feet is a measurement.
First, convert the depth to inches by dividing 2 by 12 (0.1667 ft). Next, multiply 31 ft by 21 ft by 0.1667 ft to get cubic feet (108.5 cubic feet). Finally divide 108.5 cubic feet by 27 (the number of cubic feet in a cubic yard) to get your answer (4.02 cubic yards). Hope this helps!
