To find the surface area of a cube, we need to calculate the area of all six sides.
Since the cube is made up of six squares, each with side length 3.5 inches, we can find the surface area by calculating the area of one side and then multiplying by 6.
Area of one side = 3.5 inches * 3.5 inches = 12.25 square inches
Surface area of cube = 6 * 12.25 square inches = 73.5 square inches
Therefore, the surface area of the cube is 73.5 square inches.
