What is the surface area of a rectangular prism?

Back

The surface area of a rectangular prism is the total area of all its faces. It can be calculated using the formula: Surface Area = 2(lw + lh + wh), where l is length, w is width, and h is height.

What is a net in geometry?

Back

A net is a two-dimensional representation of a three-dimensional shape. It shows all the faces of the shape laid out flat.

Front

What is the formula for finding the area of a rectangle?

Back

Area = length × width.

Front

What is the surface area of a cube?

Back

The surface area of a cube is calculated using the formula: Surface Area = 6a², where a is the length of one side.

Front

What is a rectangular prism?

Back

A rectangular prism is a three-dimensional shape with six rectangular faces, where opposite faces are equal.

Front

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

Back

Surface Area = (Base Area × 2) + (Perimeter of Base × Height).

Front

What is the difference between area and surface area?

Back

Area measures the size of a two-dimensional surface, while surface area measures the total area of the outer surfaces of a three-dimensional object.

Front

What is the surface area of a rectangular prism with dimensions 3 cm, 4 cm, and 5 cm?

Back

Surface Area = 2(3*4 + 3*5 + 4*5) = 2(12 + 15 + 20) = 2(47) = 94 cm².
