Warm UP: S.A Pyramids

Front

What is a square pyramid?

Back

A three-dimensional geometric figure with a square base and four triangular faces that meet at a single point (the apex).

Front

How do you calculate the surface area of a pyramid?

Back

The surface area of a pyramid is calculated by adding the area of the base to the area of the triangular faces. For a square pyramid, the formula is: Surface Area = Base Area + (1/2 * Perimeter of Base * Slant Height).

Front

What is the formula for the area of a triangle?

Back

Area = (1/2) * base * height.

Front

What is a triangular pyramid?

Back

A three-dimensional geometric figure with a triangular base and three triangular faces that meet at a single point (the apex).

Front

What is the surface area of a triangular pyramid with a base area of 50 m² and a slant height of 10 m?

Back

Surface Area = Base Area + (1/2 * Perimeter of Base * Slant Height). Calculate the perimeter and apply the formula.

Front

What is the difference between a prism and a pyramid?

Back

A prism has two parallel bases and rectangular faces, while a pyramid has one base and triangular faces that converge at a point.

Front

What is a regular pyramid?

Back

A pyramid with a base that is a regular polygon and all its lateral faces are congruent isosceles triangles.

Front

How do you find the surface area of a regular pyramid?

Back

Surface Area = Base Area + (1/2 * Perimeter of Base * Slant Height).

Front

What is the perimeter of a square with a side length of 4 m?

Back

Perimeter = 4 * side length = 4 * 4 m = 16 m.

Front

What is the base area of a square pyramid with a base side length of 5 m?

Back

Base Area = side length² = 5 m * 5 m = 25 m².
