Volume of Pyramids Flashcards

The volume of a pyramid is calculated using the formula: (1/3) × Base Area × Height.

The base area is the area of the shape at the bottom of the pyramid (e.g., square, rectangle, triangle).

The height is the perpendicular distance from the base to the apex (top point) of the pyramid.

The unit for volume is cubic units, e.g., cm³, m³.

For a square-based pyramid, the base area is the area of the square: side × side.

For a triangular-based pyramid, the base area is the area of the triangle: (1/2) × base × height of the triangle.

Always calculate the base area first before multiplying by the height and dividing by 3.

Doubling the height of a pyramid doubles its volume, as height is directly proportional to volume.

Doubling the base area of a pyramid doubles its volume, as base area is directly proportional to volume.

A common mistake is forgetting to divide by 3 after multiplying the base area by the height.
