Question

what is the surface area of the rectangular prism below?
a. 248 units²
b. 980 units²
c. 496 units²
d. 490 units²

Explanation:

Step1: Recall the formula for the surface area of a rectangular prism

The formula for the surface area \(S\) of a rectangular prism is \(S = 2(lw+lh + wh)\), where \(l\) is the length, \(w\) is the width, and \(h\) is the height.

Step2: Identify the values of \(l\), \(w\), and \(h\)

From the problem, \(l = 14\), \(w=7\), and \(h = 7\).

Step3: Substitute the values into the formula
