9x12 feet at 4 inches deep: 1.3 cubic yards.
The number of concrete blocks that make up a foot depends on the size of the blocks. Standard concrete blocks, often referred to as cinder blocks, typically measure 16 inches long, 8 inches high, and 8 inches deep. To cover a linear foot, you would need about 0.75 of a standard 16-inch block to reach a total of one foot in length.
An 80lb bag of concrete you can at your local home improvement store covers about 4 square foot at 2" thick. So you would need about 144 bags of 80lb concrete.
6 inches = 1/2 footVolume = (surface area) x (depth) = 450 x 1/2 = 225 cubic feet = 81/3 cubic yards.
To calculate the volume of concrete needed for footings that are 28 feet long, 2 feet wide, and 3 feet deep, use the formula for volume: length × width × depth. This results in a volume of 28 ft × 2 ft × 3 ft = 168 cubic feet. Therefore, you will need 168 cubic feet of concrete for the footings.
