Surface Area of Triangular Prisms

Front

What is surface area?

Back

The sum of all the areas of all the shapes that cover the object.

Front

What is a triangular prism?

Back

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

Front

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

Back

Surface Area = (Base Area x 2) + (Perimeter of Base x Height of Prism)

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 x base x height.

Front

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

Back

Area = 1/2 x 10 cm x 5 cm = 25 cm².

Front

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

Back

Perimeter = 3 cm + 4 cm + 5 cm = 12 cm.

Front

What is the height of a triangular prism?

Back

The distance between the two triangular bases.

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) + (Perimeter x 10 cm).

Front

What is the surface area of a triangular prism with a base perimeter of 12 cm and height of 5 cm?

Back

Surface Area = (Base Area x 2) + (12 cm x 5 cm).

Front

What units are used to measure surface area?

Back

Square units, such as cm², m², ft².
