Surface Area of Triangular Prisms

Front

What is a triangular prism?

Back

A three-dimensional shape with two triangular bases and three rectangular faces.

Front

What is the formula for Total Surface Area of a Triangular Prism?

Back

S = Ph + 2B, where P is the perimeter of the base, h is the height, and B is the area of the base.

Front

What is the formula for Lateral Surface Area of a Triangular Prism?

Back

S = Ph, where P is the perimeter of the base and h is the height.

Front

What does 'P' represent in the surface area formulas?

Back

'P' represents the perimeter of the triangular base.

Front

What does 'B' represent in the surface area formulas?

Back

'B' represents the area of the triangular base.

Front

How do you calculate the area of a triangle?

Back

Area = 1/2 * base * height.

Front

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

Back

Area = 1/2 * 5 * 4 = 10 cm².

Front

What is the height of a prism?

Back

The distance between the two triangular bases.

Front

What is the difference between Total Surface Area and Lateral Surface Area?

Back

Total Surface Area includes all faces, while Lateral Surface Area includes only the side faces.

Front

If a triangular prism has a height of 10 cm and a perimeter of the base of 12 cm, what is the Lateral Surface Area?

Back

Lateral Surface Area = Ph = 12 * 10 = 120 cm².
