Surface Area of Rectangular Prisms Pizzaz

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

If a rectangular prism has a length of 5m, width of 3m, and height of 2m, what is its surface area?

Back

Surface Area = 2(5*3 + 5*2 + 3*2) = 2(15 + 10 + 6) = 2(31) = 62m².

Front

What units are used to measure surface area?

Back

Square units (e.g., square meters, square inches).

Front

How does increasing the dimensions of a rectangular prism affect its surface area?

Back

Increasing the dimensions increases the surface area.

Front

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

Back

Surface Area = 6 * (side length)² = 6 * (4)² = 6 * 16 = 96cm².

Front

If the length of a rectangular prism is doubled, what happens to the surface area?

Back

The surface area increases, but the exact change depends on the other dimensions.

Front

What is the surface area of a rectangular prism with dimensions 10in x 5in x 2in?

Back

Surface Area = 2(10*5 + 10*2 + 5*2) = 2(50 + 20 + 10) = 2(80) = 160in².

Front

What is the relationship between surface area and volume in a rectangular prism?

Back

Surface area measures the total area of the surfaces, while volume measures the space inside the prism.

Front

How do you find the surface area of two identical rectangular prisms?

Back

Calculate the surface area of one prism and multiply by 2.

Front

What is the surface area of a rectangular prism with a length of 8m, width of 3m, and height of 4m?

Back

Surface Area = 2(8*3 + 8*4 + 3*4) = 2(24 + 32 + 12) = 2(68) = 136m².
