The surface area of a rectangular prism is calculated using the formula: 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.

Step 1: Substitute the given values into the formula.
= 2(15cm)(4cm) + 2(15cm)(9cm) + 2(4cm)(9cm)

Step 2: Calculate each term.
= 2(60cm^2) + 2(135cm^2) + 2(36cm^2)

Step 3: Simplify the equation.
= 120cm^2 + 270cm^2 + 72cm^2

Step 4: Add all the terms together to get the total surface area.
= 462cm^2

So, the surface area of the rectangular prism is 462 square centimeters.
