You need to specify the depth also.
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.
30 feet = 9.144 metres
The answer would be 10 yards. Each yard is equal to 3 feet.
30 yards=90 feet
30 meters = 98.42 feet
About 3.
Typically you would need about 30% more type I cement to attain the same early strength gain as Type III cement.

I 'm guessing probably around 30 dollars.

To calculate the number of 80 lb bags of cement needed for a 10x12 foot slab that is 3 inches thick, first determine the volume of the slab in cubic feet: 10 ft x 12 ft x (3/12) ft = 30 cubic feet. One 80 lb bag of cement typically yields about 0.6 cubic feet of concrete. Therefore, you would need approximately 30 / 0.6 = 50 bags of 80 lb cement to complete the slab.
There is no possible way to find this. However, one can find the volume of a pyramid by simply using this formula: V=bh1/3
30 yards=90 feet
30 meters = 98.42 feet
It could be many different sizes. An example would be a rectangle, 30 feet by 40 feet.
9.144 meters in 30 feet.
