Surface area of a cube = 486 square inches

Solution:

Given each side of a cube = 9 inches

Net of a cube has 6 squares.

Area of square = side × side

Area of 1 square = 9 × 9 = 81 square inches

Surface area of a cube = Area of 6 squares

= 6 × (side × side)

= 6 × 81

= 486 square inches

Hence, surface area of a cube is 486 square inches.
