Surface Area of Triangular Prisms with Nets

Front

What is the surface area of a triangular prism?

Back

The surface area of a triangular prism is the total area of all its faces, including the two triangular bases and the three rectangular lateral faces.

Front

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

Back

To calculate the surface area, use the formula: Surface Area = (Base Area x 2) + (Perimeter of Base x Height of Prism).

Front

What is a net of a triangular prism?

Back

A net of a triangular prism is a two-dimensional representation that shows all the faces of the prism laid out flat.

Front

What are the components of a triangular prism?

Back

A triangular prism has two triangular bases and three rectangular lateral faces.

Front

If the base of a triangular prism is 5 cm and the height is 4 cm, what is the area of the base?

Back

The area of the triangular base is 10 cm² (Area = 1/2 x base x height = 1/2 x 5 cm x 4 cm).

Front

What is the perimeter of a triangle with sides 3 cm, 4 cm, and 5 cm?

Back

The perimeter is 12 cm (Perimeter = 3 cm + 4 cm + 5 cm).

Front

How do you find the height of a triangular prism?

Back

The height of a triangular prism is the distance between the two triangular bases.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula: Area = 1/2 x base x height.

Front

If a triangular prism has a height of 10 cm and a base area of 20 cm², what is the total surface area?

Back

Total Surface Area = (Base Area x 2) + (Perimeter of Base x Height). If Perimeter is 12 cm, then Total Surface Area = (20 cm² x 2) + (12 cm x 10 cm) = 40 cm² + 120 cm² = 160 cm².

Front

What is the total surface area of a triangular prism with a base area of 15 cm² and a perimeter of 18 cm, and a height of 5 cm?

Back

Total Surface Area = (15 cm² x 2) + (18 cm x 5 cm) = 30 cm² + 90 cm² = 120 cm².
