Surface Area of Prisms

Front

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

Back

The lateral surface area (LSA) of a prism can be calculated using the formula: LSA = perimeter of the base × height.

Front

What is the total surface area of a prism?

Back

The total surface area (TSA) of a prism is the sum of the lateral surface area and the area of the two bases. TSA = LSA + 2 × area of the base.

Front

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

Back

Lateral surface area refers to the area of the sides of the prism, while total surface area includes the lateral area plus the area of the bases.

Front

How do you find the perimeter of a base of a prism?

Back

To find the perimeter of a base of a prism, add the lengths of all the sides of the base shape.

Front

What units are used for measuring surface area?

Back

Surface area is measured in square units, such as square millimeters (mm²), square centimeters (cm²), or square inches (in²).

Front

If a prism has a height of 10 cm and a base perimeter of 20 cm, what is its lateral surface area?

Back

The lateral surface area is calculated as LSA = perimeter of the base × height = 20 cm × 10 cm = 200 cm².

Front

What is the area of a rectangle with a length of 5 cm and a width of 3 cm?

Back

The area of a rectangle is calculated as Area = length × width = 5 cm × 3 cm = 15 cm².

Front

How do you calculate the area of a triangular base?

Back

The area of a triangle is calculated using the formula: Area = 1/2 × base × height.

Front

What is the lateral surface area of a cylinder?

Back

The lateral surface area of a cylinder is calculated using the formula: LSA = 2πrh, where r is the radius and h is the height.

Front

What is the significance of the height of a prism in surface area calculations?

Back

The height of a prism is crucial for calculating the lateral surface area, as it determines how tall the sides of the prism are.
