Surface Area

Front

What is Surface Area?

Back

The total area that the surface of an object occupies.

Front

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

Back

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

Front

What is Lateral Surface Area?

Back

The area of the sides of a three-dimensional figure, excluding the bases.

Front

How do you calculate the lateral surface area of a cylinder?

Back

Lateral Surface Area = 2πrh, where r = radius and h = height.

Front

What is Total Surface Area?

Back

The sum of the lateral surface area and the area of the bases.

Front

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

Back

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

Front

What is the lateral surface area of a rectangular prism with dimensions 10 cm x 5 cm x 4 cm?

Back

Lateral Surface Area = 2h(l + w) = 2*4(10 + 5) = 120 cm².

Front

What is the total surface area of a cube with side length 3 cm?

Back

Total Surface Area = 6s² = 6(3)² = 54 cm².

Front

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

Back

Lateral surface area includes only the sides, while total surface area includes the sides and the bases.

Front

How do you find the surface area of a sphere?

Back

Surface Area = 4πr², where r = radius.
