Surface Area of Square Based Pyramids

Front

What is the formula for the surface area of a square-based pyramid?

Back

Surface Area = Base Area + Lateral Area = s² + 2sl, where s is the side length of the base and l is the slant height.

Front

If the side length of the base of a pyramid is 4 cm and the slant height is 5 cm, what is the surface area?

Back

Surface Area = 4² + 2(4)(5) = 16 + 40 = 56 cm².

What is the unit of measurement for surface area?

Back

The unit of measurement for surface area is square units, such as cm², m², ft², or in².

Front

What is the significance of the slant height in calculating the surface area of a pyramid?

Back

The slant height is crucial for calculating the lateral area, which contributes to the total surface area.

Front

If a square-based pyramid has a base area of 100 cm² and a lateral area of 200 cm², what is its total surface area?

Back

Total Surface Area = Base Area + Lateral Area = 100 cm² + 200 cm² = 300 cm².
