Q:

# What is the formula for the surface area of a pyramid?

A:

The formula for calculating the total surface area of a pyramid is: S = (1/2)Pl + B. The surface area of a pyramid is the total sum of the lateral area combined with the area of the base.

The letter S in the equation represents the total surface area, and the P symbolizes the perimeter of the base. The l represents the slant height of the objects, and the B represents the area of the base.

When writing or typing this formula, it is important to not confuse the lowercase l with an uppercase I. The two letters appear identical when typed in some fonts. The lowercase l is the letter used in the equation.
