Question

translate the sentence into an equation or formula. the surface area sa of a rectangular prism is 2 times the sum of the width (w) times height (h), and length (l) times width, and length times height.

Explanation:

Step1: Identify the sum part

The sum is of $w\times h$, $l\times w$ and $l\times h$, which can be written as $(wh + lw+lh)$.

Step2: Multiply by 2

The surface - area SA is 2 times the sum, so the equation is $SA = 2(wh + lw + lh)$.

Answer:

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