Surface Area of Pyramids

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 (Base x Height)

Front

How do you calculate the surface area of a square pyramid?

Back

Surface Area = Base Area + Lateral Area, where Lateral Area = 1/2 x Perimeter of Base x Slant Height.

Front

What is the surface area of a square pyramid with a base of 5 m and a height of 12 m?

Back

Surface Area = 5^2 + 1/2 x (4 x 5) x 13 = 25 + 130 = 155 m².

Front

What is the lateral area of a square pyramid?

Back

Lateral Area = 1/2 x Perimeter of Base x Slant Height.

Front

If the base of a square pyramid is 6 cm and the slant height is 10 cm, what is the lateral area?

Back

Lateral Area = 1/2 x (4 x 6) x 10 = 120 cm².

Front

What is the surface area of a square pyramid with a base area of 64 cm² and a lateral area of 96 cm²?

Back

Surface Area = Base Area + Lateral Area = 64 cm² + 96 cm² = 160 cm².

Front

What is the definition of surface area?

Back

Surface area is the total area that the surface of a three-dimensional object occupies.

Front

How do you find the surface area of a pyramid with a triangular base?

Back

Surface Area = Base Area + Lateral Area, where Lateral Area = 1/2 x Perimeter of Base x Slant Height.

Front

What is the formula for the area of a square?

Back

Area = Side x Side.

Front

If a square pyramid has a base side of 4 m and a height of 3 m, what is the surface area?

Back

Surface Area = 4^2 + 1/2 x (4 x 4) x 5 = 16 + 40 = 56 m².
