Surface Area of Prisms

Front

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

Back

The surface area (SA) of a rectangular prism is given by the formula: SA = 2(lw + lh + wh), where l is the length, w is the width, and h is the height.

Front

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

Back

The surface area (SA) of a triangular prism is given by the formula: SA = bh + lP, where b is the base of the triangle, h is the height of the triangle, l is the length of the prism, and P is the perimeter of the triangular base.

Front

What is lateral surface area?

Back

Lateral surface area refers to the area of the sides of a three-dimensional shape, excluding the area of the bases.

Front

How do you calculate the lateral surface area of a rectangular prism?

Back

The lateral surface area (LSA) of a rectangular prism can be calculated using the formula: LSA = 2h(l + w), where h is the height, l is the length, and w is the width.

Front

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

Back

The lateral surface area (LSA) of a triangular prism can be calculated using the formula: LSA = lP, where l is the length of the prism and P is the perimeter of the triangular base.

Front

What is the significance of the base area in calculating the surface area of prisms?

Back

The base area is crucial in calculating the total surface area of prisms as it contributes to the overall surface area along with the lateral surface area.

Front

What units are used to measure surface area?

Back

Surface area is measured in square units, such as square centimeters (cm²), square meters (m²), etc.

Front

What is the total surface area of a prism?

Back

The total surface area of a prism is the sum of the lateral surface area and the area of the two bases.

Front

How do you find the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = length × width.

Front

How do you find the area of a triangle?

Back

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