01/29 Surface Area Prisms

Front

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

Back

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

Front

How do you find the surface area of a prism?

Back

Calculate the area of the base and multiply by the height, then add the lateral area.

Front

What is lateral area in the context of prisms?

Back

Lateral area is the sum of the areas of the sides of the prism, excluding the top and bottom.

Front

What is the surface area of a rectangular prism with dimensions 5 cm (length), 9 cm (width), and 20 cm (height)?

Back

650 cm².

Front

What is the total surface area of a prism with a base area of 50 square feet and a height of 2 feet?

Back

Total Surface Area = 2 * Base Area + Lateral Area.

Front

What 3D solid is formed by a triangular base and three rectangular faces?

Back

Triangular Prism.

Front

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

Back

Lateral Area = perimeter of the base × height.

Front

What is the surface area of a rectangular prism with dimensions 10 in. (length), 5 in. (width), and 4 in. (height)?

Back

Surface Area = 2(10*5 + 10*4 + 5*4) = 2(50 + 40 + 20) = 220 in².

Front

What is the difference between surface area and volume?

Back

Surface area measures the total area of the surface of a 3D object, while volume measures the space inside the object.

Front

What is the surface area of a prism with a base area of 30 square feet and a height of 5 feet?

Back

Total Surface Area = 2 * Base Area + Lateral Area = 2*30 + (Perimeter of Base * Height).
