Surface Area of Prisms

Front

What is surface area?

Back

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

Front

What does 'h' stand for in the surface area formulas?

Back

Distance between bases.

Front

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

Back

S = P h + 2 B, 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 the lateral surface area of a prism?

Back

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

Front

How do you calculate the area of the base of a rectangular prism?

Back

Area = length × width.

Front

What is the perimeter of a base?

Back

The total distance around the base shape.

Front

If a prism has a base area of 50 cm² and a height of 4 cm, what is the total surface area?

Back

S = P h + 2B; calculate P first, then use the formula.

Front

What is the difference between lateral surface area and total surface area?

Back

Lateral surface area includes only the sides, while total surface area includes the sides and the bases.

Front

If the perimeter of the base is 20 cm and the height is 5 cm, what is the lateral surface area?

Back

S = P h = 20 cm × 5 cm = 100 cm².

Front

What units are used to measure surface area?

Back

Square units, such as cm², in², m².
