Surface Area of Rectangular Prism Net

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

What does surface area represent in a real-world context?

Back

Surface area represents the total area that the surface of an object occupies, such as the amount of wrapping paper needed to cover a gift.

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(5*3 + 5*4 + 3*4) = 2(15 + 20 + 12) = 2(47) = 94 cm².

Front

What is the surface area of a rectangular prism with dimensions 2 m, 3 m, and 4 m?

Back

Surface Area = 2(2*3 + 2*4 + 3*4) = 2(6 + 8 + 12) = 2(26) = 52 m².

Front

What shape is the base of a rectangular prism?

Back

The base of a rectangular prism is a rectangle.

Front

How does the surface area of a rectangular prism change if the dimensions are doubled?

Back

If the dimensions are doubled, the surface area increases by a factor of 4.

Front

What is the total surface area of a rectangular prism with a length of 6 inches, width of 2 inches, and height of 3 inches?

Back

Surface Area = 2(6*2 + 6*3 + 2*3) = 2(12 + 18 + 6) = 2(36) = 72 square inches.

Front

Why is it important to calculate surface area in real life?

Back

Calculating surface area is important for tasks like painting, wrapping, and packaging, where knowing the area helps determine the amount of material needed.

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)² = 6 * 16 = 96 cm².

Front

If a rectangular prism has a surface area of 100 cm² and a height of 5 cm, how can you find the base area?

Back

Base Area = (Surface Area - 2 * (height * width)) / 2.
