Total Surface Area of Prisms using Nets

Front

What is the total surface area of a prism?

Back

The total surface area of a prism is the sum of the areas of all its faces, including the bases.

Front

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

Back

The lateral surface area of a prism can be calculated by finding the perimeter of the base and multiplying it by the height of the prism.

What is a net in geometry?

Back

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

Front

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

Back

Lateral Surface Area = 2h(l + w), where h is the height, l is the length, and w is the width.

Front

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

Back

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

Front

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

Back

Lateral Surface Area = Perimeter of the base × Height.

Front

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

Back

Total Surface Area = Lateral Surface Area + 2 × Area of the base.

Front

If the base of a triangular prism has a perimeter of 30 cm and the height is 10 cm, what is the lateral surface area?

Back

Lateral Surface Area = 30 cm × 10 cm = 300 cm².

Front

What is the area of a triangle with a base of 6 cm and a height of 4 cm?

Back

Area = 1/2 × base × height = 1/2 × 6 cm × 4 cm = 12 cm².

Front

How do you find the area of a rectangle?

Back

Area = length × width.
