Question

find the surface area of the rectangular prism.
6 in
5 in
3 in
answer
in²

Explanation:

Step1: Recall the surface area formula

The formula for the surface area \(S\) of a rectangular prism is \(S = 2(lw+lh + wh)\), where \(l\) is length, \(w\) is width, and \(h\) is height. Here, \(l = 5\) in, \(w=3\) in, \(h = 6\) in.

Step2: Calculate \(lw\), \(lh\), and \(wh\)

• \(lw=5\times3 = 15\)
• \(lh=5\times6=30\)
• \(wh=3\times6 = 18\)

Step3: Substitute into the formula
