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.
