How many square feet will a ton of salt cover?
To determine how many slabs of stone you need, first convert the area from square feet to square inches. Since 1 square foot equals 144 square inches, 133 square feet is 133 x 144 = 19,152 square inches. Then, divide the total area by the area of one slab: 19,152 ÷ 40 = 478.8. Therefore, you would need 479 slabs of stone to cover 133 square feet, rounding up to the nearest whole slab.
