It depends on how deep it is. If it is 6 inches deep, you will need 77 yards.

To determine the number of cement blocks needed for a 20-foot by 30-foot building, you'll first need to calculate the total wall area. Assuming an 8-foot wall height, the perimeter is 100 feet (20+30+20+30), resulting in a wall area of 800 square feet (100 feet x 8 feet). If each standard cement block is approximately 1.125 square feet, you would need around 711 blocks (800 ÷ 1.125). This estimate does not account for doors, windows, or other architectural features.

3 cement bricks for foot
The amount of cement will depend on the size of the tile, since a larger trowel is needed for larger tile.
Dimensions x whatever is the going rate at your local cement contracter... usually by the square foot
To calculate the number of bags of cement needed for a 49.58 square foot area at a 4-inch depth, first convert the depth to feet: 4 inches equals 1/3 foot. The volume required is 49.58 square feet × 1/3 foot = approximately 16.53 cubic feet. If a standard bag of cement (typically 94 lbs) yields about 0.5 cubic feet, you'll need roughly 33 bags (16.53 ÷ 0.5).
