Surface Area Pyramids

Front

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

Back

The surface area (SA) of a pyramid is given by the formula: SA = Base Area + (1/2 * Perimeter of Base * Slant Height).

Front

Define 'Base Area' in the context of a pyramid.

Back

Base Area is the area of the base shape of the pyramid, which can be a triangle, square, or any polygon.

Front

What is 'Slant Height' in a pyramid?

Back

Slant Height is the distance from the apex (top point) of the pyramid to the midpoint of one of the sides of the base.

Front

How do you calculate the area of a square base?

Back

Area of a square = side length × side length.

Front

How do you calculate the area of a triangular base?

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 distance around the base shape, calculated by adding the lengths of all sides.

Front

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

Back

Base Area = 4 feet × 4 feet = 16 square feet.

Front

If a pyramid has a triangular base with a base of 6 feet and a height of 4 feet, what is the area of the base?

Back

Area = (6 feet × 4 feet) / 2 = 12 square feet.

Front

What is the surface area of a pyramid with a square base of area 25 square feet and a slant height of 10 feet?

Back

SA = 25 + (1/2 * 20 * 10) = 25 + 100 = 125 square feet.

Front

What is the significance of rounding in surface area calculations?

Back

Rounding is important to provide a clear and concise answer, especially when dealing with measurements.
