Surface Area Review

Front

What is 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 cube?

Back

To find the surface area of a cube, use the formula: Surface Area = 6 * (side length)^2.

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 does it mean to find the lateral area of a shape?

Back

Lateral area refers to the area of the sides of a three-dimensional shape, excluding the top and bottom.

Front

How do you calculate the lateral area of a cylinder?

Back

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

Front

What is a net in geometry?

Back

A net is a two-dimensional representation of a three-dimensional shape that can be folded to form the shape.

Front

What is the surface area of a sphere?

Back

The surface area of a sphere is given by the formula: Surface Area = 4πr^2, where r = radius.

Front

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

Back

Surface Area = (base area + lateral area) = 2 * (1/2 * base * height) + (perimeter of base * height).

Front

What is the difference between surface area and volume?

Back

Surface area measures the area of the surface of a shape, while volume measures the space inside the shape.

Front

What is the surface area of a cube with a side length of 4 cm?

Back

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