How many blocks to build a wall 4ft height x 8ft long?

Answer 1

To determine how many blocks are needed for a wall that is 4 feet high and 8 feet long, first calculate the area of the wall: 4 ft x 8 ft = 32 square feet. If standard concrete blocks are used, which typically measure 16 inches long by 8 inches high (1.33 ft x 0.67 ft), each block covers about 0.89 square feet. Dividing the total area (32 sq ft) by the area of one block (0.89 sq ft) gives approximately 36 blocks required, not accounting for mortar or waste.
