To find out how many 18-inch by 18-inch slabs fit into a 31-foot by 9-foot area, first convert the dimensions to inches. The area of the space is 31 ft × 12 in/ft = 372 inches and 9 ft × 12 in/ft = 108 inches, giving a total area of 372 inches × 108 inches = 40,176 square inches. The area of one slab is 18 inches × 18 inches = 324 square inches. Dividing the total area by the area of one slab, 40,176 ÷ 324, results in approximately 124 slabs.
