60. In the figure below, both solids consist of 4 cubes, each 1 unit on a side. In the solid on the right, the 4 cubes form a rectangular prism that is 2 units long, 1 unit wide, and 2 units high. The solid on the left is the result of moving Cube D from its position above Cube C to beside it so that Cubes B, C, and D form a rectangular prism 3 units long, 1 unit wide, and 1 unit high. To the nearest percent, the total surface area of the solid on the right is what percent less than the total surface area of the solid on the left?
