How many 18x18inch pavers needed for a 12 feet wide 16feet long patio?

To calculate the number of 18x18 inch pavers needed for a 12 feet by 16 feet patio, first convert the dimensions of the patio to square inches: 12 feet x 16 feet = 192 square feet, which is 27,648 square inches (since 1 square foot = 144 square inches). Each 18x18 inch paver covers 324 square inches. Dividing the total area of the patio by the area of one paver gives 27,648 ÷ 324 = 85.5. Therefore, you will need 86 pavers, rounding up to the nearest whole number.
