Find the surface area of each rectangular 5. $\ell=7 n, w=2 n, h=\frac{1}{2} n$
Final Answer: The surface area of the rectangular prism is \(\boxed{37n^2}\) square units.
Step 1 :Given a rectangular prism with length (l) = 7n, width (w) = 2n, and height (h) = 0.5n.
Step 2 :The surface area (A) of a rectangular prism is given by the formula \(A = 2lw + 2lh + 2wh\).
Step 3 :Substitute the given values into the formula: \(A = 2(7n)(2n) + 2(7n)(0.5n) + 2(2n)(0.5n)\).
Step 4 :Simplify the expression to find the surface area: \(A = 37n^2\).
Step 5 :Final Answer: The surface area of the rectangular prism is \(\boxed{37n^2}\) square units.
