8.2 Prism Surface Area Practice

Front

What is a prism?

Back

A prism is a three-dimensional shape with two parallel, congruent bases connected by rectangular faces.

Front

How do you calculate the surface area of a prism?

Back

The surface area of a prism is calculated by adding the areas of all its faces, including the bases and the lateral faces.

Front

What is the formula for the surface area of a rectangular prism?

Back

Surface Area = 2lw + 2lh + 2wh, where l = length, w = width, h = height.

Front

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

Back

Surface Area = bh + l1h + l2h + l3h, where b = base area, l1, l2, l3 = lengths of the triangular sides, and h = height.

Front

What is the area of a triangle?

Back

Area = 1/2 * base * height.

Front

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

Back

Surface Area = 20 cm² + (perimeter of base * height).

Front

What is the lateral surface area of a prism?

Back

The lateral surface area is the area of the sides of the prism, excluding the bases.

Front

How do you find the total surface area of a prism with a hexagonal base?

Back

Calculate the area of the hexagonal base and multiply by 2, then add the lateral area (perimeter of base * height).

Front

What is the significance of the height in calculating surface area?

Back

The height is crucial as it determines the size of the lateral faces of the prism.

Front

What units are used for measuring surface area?

Back

Surface area is measured in square units, such as square feet, square meters, or square inches.
