Surface Area of Pyramids

Front

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

Back

Lateral Surface Area = (Perimeter of the base × Slant height) / 2

Front

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

Back

Total Surface Area = Lateral Surface Area + Area of the Base

Front

What is a pyramid?

Back

A pyramid is a three-dimensional shape with a polygonal base and triangular faces that meet at a common point called the apex.

Front

What is the base of a pyramid?

Back

The base of a pyramid is the polygonal face on which the pyramid stands.

Front

What is the apex of a pyramid?

Back

The apex is the top point of the pyramid where all the triangular faces meet.

Front

What is slant height in a pyramid?

Back

Slant height is the distance from the apex of the pyramid to the midpoint of a side of the base.

Front

How do you find the area of a triangular face of a pyramid?

Back

Area of a triangle = (Base × Height) / 2

Front

What is the perimeter of a base?

Back

The perimeter of a base is the total length of all the sides of the polygon that forms the base.

Front

If a pyramid has a square base with a side length of 4 ft, what is the area of the base?

Back

Area of the base = Side × Side = 4 ft × 4 ft = 16 sq ft.

Front

If the lateral surface area of a pyramid is 33 sq ft, what does this represent?

Back

This represents the total area of the triangular faces of the pyramid, excluding the base.
