Question

find the surface area of the prism. sa =? cm²

Explanation:

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

The formula for the surface area (\(SA\)) of a rectangular prism is \(SA = 2(lw+lh + wh)\), 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, \(l = 19\space cm\), \(w=15\space cm\), and \(h = 5\space cm\).

Step3: Substitute the values into the formula

Step4: Calculate the final result

\(SA = 910\space cm^{2}\)

Answer:

\(910\)
