Surface Area

Front

What is the formula for calculating the surface area of a rectangular prism?

Back

Surface Area = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

Define surface area.

Back

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

Front

What is the formula for the lateral surface area of a cone?

Back

Lateral Surface Area = πrl, where r = radius and l = slant height.

Front

Calculate the surface area of a cube with a side length of 4 cm.

Back

Surface Area = 6s² = 6(4 cm)² = 96 cm².

Front

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

Back

Surface Area = 2πr(h + r), where r = radius and h = height.

Front

How do you find the surface area of a sphere?

Back

Surface Area = 4πr², where r = radius.

Front

Calculate the surface area of a cone with a radius of 3 cm and a slant height of 5 cm.

Back

Surface Area = πr(r + l) = π(3)(3 + 5) = 24π cm².

Front

What is the difference between total surface area and lateral surface area?

Back

Total surface area includes all surfaces, while lateral surface area excludes the bases.

Front

Find the surface area of a prism with a base area of 50 cm² and a height of 10 cm.

Back

Surface Area = 2 * Base Area + Perimeter of Base * Height = 2(50) + P(10).

Front

What is the formula for the surface area of a triangular prism?

Back

Surface Area = Base Area + Perimeter of Base * Height.
