Lesson 10.1 Surface Area of Triangular Prisms

Front

What does P represent in the context of a triangular prism?

Back

P represents the Perimeter of the Base.

Front

What does B represent in the context of a triangular prism?

Back

B represents the Area of the Base.

Front

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

Back

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

Front

How do you find the area of a triangle?

Back

Area = 1/2 x base x height.

Front

What is the height of a triangular prism?

Back

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

Front

What is the difference between surface area and volume?

Back

Surface area measures the total area of the surface of a 3D object, while volume measures the amount of space inside the object.

Front

If the base of a triangular prism is an equilateral triangle with a side length of 6 cm, what is the perimeter?

Back

Perimeter = 3 x side length = 3 x 6 cm = 18 cm.

Front

What is the relationship between the base area and the height in a triangular prism?

Back

The base area is multiplied by the height to find the volume of the prism.

Front

How do you calculate the perimeter of a triangular base?

Back

Add the lengths of all three sides of the triangle.

Front

What units are used for measuring surface area?

Back

Surface area is measured in square units (e.g., cm², m²).
