Surface Area of a Rectangular Prism

Hard Measurement Surface Area And Volume

A rectangular prism is formed by a base that has a length of 10 cm and a width of 6 cm. The height of the prism is twice its width. To find the total surface area of this prism, you can use the formula for surface area:

$$ SA = 2lw + 2lh + 2wh $$

where $l$ is the length, $w$ is the width, and $h$ is the height. First, determine the height of the prism based on the width, then calculate the surface area.

$144\,cm^2$

$120\,cm^2$

$156\,cm^2$

$180\,cm^2$
