Length is 13 meters, width is 15 meters, how to calculate how many flat, what is the calculation formula?


Area = length * width
=13 * 15 = 195 square meters = 195 square meters



Length 2.8 width 2.5 depth 2.5 square number, how to calculate the column formula


Surface area: L * w * 2 + W * h * 2 + L * h * 2
Headless surface area: L * w * 1 + W * h * 2 + L * h * 2



6 meters wide, 640 meters long, equal to how many square meters


640*6=3840
