Hans makes a wooden puzzle in the shape of a cube. If a single side of the cube is 3.5 inches, what is the surface area of the cube? Hint: Draw a net.
To find the surface area of a cube, we need to find the area of each of the six sides and then add them together.
Since one side of the cube is 3.5 inches, the area of each side is 3.5 * 3.5 = 12.25 square inches.
There are six sides, so the total surface area of the cube is 6 * 12.25 = 73.50 square inches.
Therefore, the surface area of the cube is 73.50 square inches.
