There are 12 inches per foot. Therefore, the volume of sand required is 100 X 122 X 5 cubic inches or 7 X 104 cubic inches, to the number of significant digits justified by the least precisely stated data point, 5 inches. If all the integers specified are considered exact, then the answer is 72,000 cubic inches.

This is a nonsensical question. What is 2.9 cubic feet?
To calculate the number of 8 x 4 inch bricks needed to cover 125 square feet, first convert the dimensions of the brick to square feet. An 8 x 4 inch brick is 0.67 square feet (8 inches = 0.67 feet, 4 inches = 0.33 feet, so 0.67 x 0.33 = 0.22 square feet). Then, divide the total area to cover (125 square feet) by the area of one brick (0.22 square feet), which gives approximately 568 bricks needed.
720 4"x 8" tiles are needed.
