To find the volume of a pyramid, you can use the formula:

$Volume=\frac{1}{3}\times Base Area\times Height$

Here’s a breakdown of the formula:

• Base Area: The area of the base of the pyramid. How you calculate this depends on the shape of the base. For example, if the base is a square, you would use the formula for the area of a square ($2^{}$side2). If the base is a rectangle, you would use the formula for the area of a rectangle ($length\times width$). For a triangular base, you’d use the formula for the area of a triangle ($\frac{1}{2}\times base\times height$), and so on.
• Height: The perpendicular distance from the base to the apex (top) of the pyramid.

So, if you know the area of the base of the pyramid and the height of the pyramid (the perpendicular height, not the slant height along the side), you can plug those values into the formula to find the volume.
