How to Calculate Concrete Blocks
Concrete is used for a variety of building purposes, including creating concrete blocks. Calculating the concrete needed to make concrete blocks can be done with a simple formula. Concrete is sold in cubic yards, so your ending measurement should reflect cubic yards. The formula for calculating concrete is: ((Length X Width X Height)/27) X 1.05 = total concrete needed plus 5 percent extra. The measurements are expressed in feet, and the 5 percent is added to ensure you have enough concrete in the event of mistakes. Does this Spark an idea?

1
Determine the length, width and height of the concrete blocks. For example, the length of the blocks is 2 feet, the width is 2 feet and the height is 2 feet.
-
2
Multiply the length times the width times the height to determine how many cubic feet of concrete you need for each block: 2 feet X 2 feet X 2 feet = 8 cubic feet.

Divide the above product by 27 (3 cubic feet X 3 cubic feet X 3 cubic feet) to determine the number of cubic yards of concrete you need for each block: 8 cubic feet/27 cubic feet = 0.296 cubic yards.
-
4
Multiply the cubic yards needed to make each block by 1.05 to derive the total concrete needed for each block plus 5 percent extra: 0.296 X 1.05 = 0.311 cubic yards.
-
5
Multiply the ending calculation by the number of blocks you wish to create. For example, if you are going to construct 10 blocks, you would calculate as follows: 0.311 cubic yards X 10 = 3.11 cubic yards of concrete.

Tips & Warnings
If you measure the blocks in inches, convert the inches to feet before completing the formula to make the ending conversion to yards easier.
Don't forget to convert cubic feet to cubic yards; otherwise, you might not purchase the appropriate amount of concrete needed to make your concrete blocks.
