How many 8x6x16 block will a yard of concrete fill?

To determine how many 8x6x16 concrete blocks a yard of concrete will fill, first calculate the volume of one block. The volume of an 8x6x16 block is 0.5 cubic feet (8 inches = 0.67 feet, 6 inches = 0.5 feet, 16 inches = 1.33 feet; thus, the volume = 0.67 x 0.5 x 1.33 = 0.447 cubic feet). Since there are 27 cubic feet in a yard of concrete, divide 27 by 0.5, which equals 54. Therefore, a yard of concrete can fill approximately 54 blocks.
