Mrs. Clark wants to paint a box. She needs to calculate the lateral surface area so that she will know how much paint to buy. The box is in the shape of a rectangular prism with the dimensions shown below. She will not paint the top and bottom bases of the box with the dimensions of 10 centimeters by 5 centimeters.

What is the lateral surface area of this rectangular prism in square centimeters?
