Question

what is the surface area? square meters submit

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 \(h\)

Here, \(l = 9\space m\), \(w = 4\space m\), and \(h=5\space m\).

Step3: Substitute the values into the formula

First, calculate \(lw\), \(lh\), and \(wh\):

• \(lw=9\times4 = 36\)
• \(lh=9\times5 = 45\)
• \(wh=4\times5 = 20\)

Then, \(lw + lh+wh=36 + 45+20=101\)

Finally, \(S = 2\times101\)

Answer:

\(202\)
