If Sam wants to make concrete blocks that are 24 inches by 24 inches by 4 inches thick. How man blocks can he make from 1 cubic yard of concrete

1 cubic yard = 27 cubic feet
Each cubic foot = 12^3 cubic inches = 1,728
27 * 1728 = total volume in cubic inches
24 * 24 * 4 = volume of block.
Divide latter into the former.
