give the formula in finding the surface area of a pyramid?​

Sagot :

Step-by-step explanation:

The general formula for the total surface area of a regular pyramid is T. S. A. =12pl+B where p represents the perimeter of the base, l the slant height and B the area of the base.

if the base of the pyramid is a triangle, then we will calculate the base with the formula: x a x t. Meanwhile, for each vertical side that will be in the form of a triangle, we will calculate it by: n ( x a x t), where n is the number of upright sides.
