each face is b wide so each face area is b x b and there are six faces so surface area is 6 x b squared
It depends on the 3D figure say u have a 3x3 cube 3x3=92 ,92x 6 (that's how many sides are on a cube) =542 There is your suface area of a 3x3 cube
Side is cube root of 125 ie 5 so suface area is 6 x 5 x 5 ie 150 squinches
1. Calculate the surface area 2. Calculate the volume 3. Divide
Area of a cube = 6 X side X side since all sides of cube are equal.
Surface area of a sphere = 4πr2
