How many 18x18 pavers to cover 7'x7'?

To cover a 7' x 7' area, first convert the dimensions to inches: 7 feet equals 84 inches. The area to cover is 84 inches x 84 inches, which equals 7,056 square inches. Each 18" x 18" paver has an area of 324 square inches (18 x 18). Dividing the total area by the area of one paver (7,056 ÷ 324) gives approximately 21.78, so you would need 22 pavers to cover the area.
