How it's calculated
Box = 2(lw + lh + wh) Cylinder = 2πr(r + h) Sphere = 4πr² Cone = πr(r + √(r² + h²)) Square pyramid = b² + 2b√((b/2)² + h²)
Gives the total outside area of five common solids, the area you would paint, wrap or clad. For a cube enter the same length, width and height. Heights are perpendicular (straight up), not along the slope.
