12 Hank wants to paint a rectangular prism that is 4 feet by 2 feet by 15 feet . How many square feet will he paint if he paints every side once?

## Step 1<br />The problem involves finding the total surface area of a rectangular prism. The formula for the surface area of a rectangular prism is given by:<br />### \(2lw + 2lh + 2wh\)<br />where \(l\) is the length, \(w\) is the width, and \(h\) is the height of the prism.<br /><br />## Step 2<br />In this problem, the dimensions of the rectangular prism are given as \(l = 15\) feet, \(w = 4\) feet, and \(h = 2\) feet.<br /><br />## Step 3<br />Substitute these values into the formula to find the total surface area.
