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.
To calculate the amount of cement needed for a volume of 30 feet long, 16 feet wide, and 4 feet deep, first find the volume: 30 × 16 × 4 = 1,920 cubic feet. If you are using a standard concrete mix, you'll generally need about 1 cubic yard of concrete for every 27 cubic feet. Therefore, you would need approximately 71.11 cubic yards of concrete for this project. Be sure to adjust for waste and specific mix designs as needed.
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.
The answer would be 10 yards. Each yard is equal to 3 feet.
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.
