Question

A right rectangular prism has a length of 8 centimeters, a width of 3 centimeters, and a height of 5 centimeters.

What is the surface area of the prism?

Answer 1

You can use the following formula to calculate the surface area of the right rectangular prism:

`\sf SA=2(wl+lh+hw)`

Where "w" is the width, "l" is the length, and "h" is the height.

Knowing that this right rectangular prism has a length of 8 centimeters, a width of 3 centimeters and a height of 5 centimeters, you can substitute these values into the formula.

Then, the surface of the right rectangular prism is:

`\sf SA=[(3 \ cm* 8 \ cm)+( 8 \ cm* 5 \ cm)+(5 \ cm*3 \ cm)]`

`\Rightarrow\sf SA=158 \ cm^2`
