Question

1. what is the formula for calculating the area of a pyramid?

$a = \frac{1}{2}pl + b$
$a = 6s^2$
$a = 4\pi r^2$
$a = \frac{1}{2}bh$

Explanation:

• $A = 6s^2$ is the surface area of a cube.
• $A = 4\pi r^2$ is the surface area of a sphere.
• $A = \frac{1}{2}bh$ is the area of a triangle.
• $A = \frac{1}{2}pl + B$ is the total surface area of a pyramid, where $p$ is the perimeter of the base, $l$ is the slant height, and $B$ is the area of the base.

Answer:

A. $A = \frac{1}{2}pl + B$
