Question

1 a. find the surface area of this rec angular prism.

Explanation:

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

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

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

From the figure, \(l = 6\), \(w=3\), and \(h = 7\).

Step3: Substitute the values into the formula
