Question

a company is going to make a storage container with sheet steel walls. the container will be in the shape of a rectangular prism, as shown below. if the sheet steel costs $30 for each square meter, how much will the sheet steel cost in total?

Explanation:

Step1: Calculate the surface area of the rectangular prism

The surface area formula for a rectangular prism is \(S = 2(lw+lh + wh)\). Here, \(l = 7m\), \(w = 3m\), \(h = 3m\).

Step2: Calculate the total cost

Since the cost per square - meter is \(\$30\), the total cost \(C=30\times S\). Substitute \(S = 102\) into the formula: \(C = 30\times102=\$3060\)

Answer:

\(3060\)
