Surface Area of Pyramids Flashcards

The total area of all the faces of the pyramid, including the base and triangular sides.

The flat, polygonal face at the bottom of the pyramid.

The perpendicular height from the base to the apex along the triangular face of the pyramid.

The triangular faces that connect the base to the apex.

Surface area = Area of the base + Sum of the areas of the triangular faces.

Calculate the area of the polygonal base using the appropriate formula (e.g., for a square base, use side²).

Use the formula 1/2 × base × slant height for each triangular face.

A pyramid with a base that is a regular polygon and identical triangular faces.

1. Find the area of the base. 2. Find the area of each triangular face. 3. Add all the areas together.

Surface area is measured in square units, such as cm² or m².
