Lateral SA of Triangular Prisms

Front

What is lateral surface area?

Back

The area of only the sides (not including the bases or top and bottom).

Front

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

Back

Lateral Surface Area = Perimeter of the base × Height of the prism.

Front

What is the formula for the perimeter of a triangle?

Back

Perimeter = Sum of all sides of the triangle.

Front

If a triangular prism has a height of 10 cm and a base perimeter of 24 cm, what is the lateral surface area?

Back

Lateral Surface Area = 24 cm × 10 cm = 240 cm².

Front

What units are used to measure lateral surface area?

Back

Square units (e.g., cm², m², in²).

Front

What is the lateral surface area of a triangular prism with a height of 5 m and a base perimeter of 30 m?

Back

Lateral Surface Area = 30 m × 5 m = 150 m².

Front

What is the lateral surface area of a triangular prism with a height of 8 cm and a base perimeter of 16 cm?

Back

Lateral Surface Area = 16 cm × 8 cm = 128 cm².

Front

If the lateral surface area of a triangular prism is 840 m² and the height is 20 m, what is the perimeter of the base?

Back

Perimeter = Lateral Surface Area ÷ Height = 840 m² ÷ 20 m = 42 m.

Front

What is the lateral surface area of a triangular prism with a height of 12 in and a base perimeter of 24 in?

Back

Lateral Surface Area = 24 in × 12 in = 288 in².

Front

If a triangular prism has a lateral surface area of 480 cm² and a height of 15 cm, what is the perimeter of the base?

Back

Perimeter = Lateral Surface Area ÷ Height = 480 cm² ÷ 15 cm = 32 cm.
