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.

Question

? square inches

Answer 1

To find the surface area of a cube, we need to calculate the area of all six sides and then add them together.

Each side of the cube is a square with side length 3.5 inches. Therefore, the area of each side is:

Area of one side = 3.5 inches x 3.5 inches = 12.25 square inches

Since there are six sides in a cube, the total surface area of the cube is:

Surface area = 6 x Area of one side = 6 x 12.25 = 73.5 square inches

Therefore, the surface area of the cube is 73.5 square inches.
