Surface Area of Triangular Prisms

Front

What is the formula to find the area of a triangle?

Back

Area = 1/2 (Base x Height)

Front

What is a triangular prism?

Back

A 3D solid with two triangular bases and three rectangular faces.

Front

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

Back

Total Surface Area = (Base Area x 2) + Lateral Surface Area.

Front

What does 'lateral surface area' refer to in a prism?

Back

The area of the sides of the prism, excluding the bases.

Front

If the base of a triangle is 10 cm and the height is 5 cm, what is the area?

Back

Area = 1/2 (10 cm x 5 cm) = 25 cm².

Front

What is the significance of 'Capital B' in prism formulas?

Back

Capital B represents the area of the base of the prism.

Front

How many faces does a triangular prism have?

Back

A triangular prism has 5 faces.

Front

What is the relationship between the base and height of a triangle?

Back

The base and height are perpendicular to each other and are used to calculate the area.

Front

If a triangular prism has a base area of 30 cm² and a height of 10 cm, what is the total surface area?

Back

Total Surface Area = (30 cm² x 2) + Lateral Surface Area.

Front

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

Back

Lateral Surface Area = Perimeter of Base x Height.
