Front

What is Surface Area?

Back

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

Front

How do you calculate the surface area of a rectangular prism?

Back

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

Front

What is the surface area of a cube with side length 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

What is the surface area of a cone?

Back

Surface Area = πr(r + l), where r = radius and l = slant height.

Front

If a rectangular prism has dimensions 3 cm, 4 cm, and 5 cm, what is its surface area?

Back

Surface Area = 2(3*4 + 3*5 + 4*5) = 94 cm².

Front

What is the surface area of a triangular prism with a base area of 20 cm² and height of 10 cm?

Back

Surface Area = base area + perimeter of base * height.

Front

What is the surface area of a cylinder with a radius of 3 cm and height of 5 cm?

Back

Surface Area = 2π(3)(5 + 3) = 150.8 cm².

Front

How do you find the total surface area of a prism?

Back

Add the areas of all the faces of the prism.
