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 many faces does a rectangular prism have?

Back

A rectangular prism has 6 faces.

Front

What is the surface area of a cube with a side length of 5 cm?

Back

Surface Area = 6 * (side length)^2 = 6 * (5 cm)^2 = 150 cm².

Front

If a rectangular prism has a length of 10 cm, width of 4 cm, and height of 3 cm, what is its surface area?

Back

Surface Area = 2(10*4 + 10*3 + 4*3) = 2(40 + 30 + 12) = 2(82) = 164 cm².

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 amount of space inside the object.

Front

What units are used to measure surface area?

Back

Surface area is measured in square units, such as cm², m², or in².

Front

How do you find the surface area of a rectangular prism with a square base?

Back

Use the formula: Surface Area = 2(base area) + perimeter of base * height.

Front

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

Back

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

Front

If the length of a rectangular prism is doubled, how does that affect the surface area?

Back

The surface area increases, as it is dependent on the dimensions of the prism.

Front

What is the surface area of a cube with a side length of 12 m?

Back

Surface Area = 6 * (12 m)^2 = 864 m².
