Surface Area

The total area of the exterior surface of a solid. Many formulas for the area of a surface are given below.

For the following tables,
h = height of solids = slant heightP = perimeter or circumference of the base
l = length of solidB = area of the baser = radius of sphere
w = width of solidR = radius of the basea = length of an edge
