Surface Area Prisms

Front

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

Back

Surface Area = Ph + 2B, where P is the perimeter of the base, h is the height, and B is the area of the base.

Front

What does 'B' represent in the surface area formula Ph + 2B?

Back

B stands for the area of the base.

Front

How do you calculate the area of a rectangle?

Back

Area = Length x Width.

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 top and bottom.

Front

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

Back

Lateral Surface Area = Perimeter of the base x Height.

Front

What is the surface area of a cube with a side length of 4 cm?

Back

Surface Area = 6 * (side length)^2 = 6 * (4 cm)^2 = 96 cm².

Front

If a rectangular prism has a length of 5 cm, width of 3 cm, and height of 4 cm, what is its surface area?

Back

Surface Area = 2(Length x Width + Length x Height + Width x Height) = 2(5*3 + 5*4 + 3*4) = 2(15 + 20 + 12) = 2(47) = 94 cm².

Front

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

Back

Total surface area includes all faces of the prism, while lateral surface area only includes the side faces.

Front

How do you find the surface area of a triangular prism?

Back

Surface Area = (Base Area + Lateral Area), where Base Area is the area of the triangular base and Lateral Area is the sum of the areas of the three rectangular sides.

Front

What is the formula for the area of a triangle?

Back

Area = (Base x Height) / 2.
