54 square feet.
A cube has 6 identical surfaces. A 3 ft cube has 6 surfaces each measuring 3ft x 3ft = 9 sq.ft. per surface. So 9 x 6 = 54 sq. ft. total surface area.

To find the total surface area of the 3-cube tower, we need to calculate the surface area of each cube individually and then add them together. The surface area of a cube is given by 6 times the side length squared. For the 3-inch cube: 6 * 3^2 = 54 square inches For the 2-inch cube: 6 * 2^2 = 24 square inches For the 1-inch cube: 6 * 1^2 = 6 square inches Adding these together: 54 + 24 + 6 = 84 square inches Therefore, the total surface area of the 3-cube tower is 84 square inches.

6 x 2^2 = 6 x 4 = 24 cm^3
6 cmgiven that a cube has L=W=H,the surface area = 6x² (6 from 6 sides, and x² because, as mentioned, L=W=H)216 = 6x²36 = x²x = 6
A cube has 6 squares as the faces of a cube. The area of the square is A = s² where s is the length of the side. Given that area formula, we have: A = (3 centimeters)² = 9 centimeters² So the area of each face of a cube is 9 centimeters²
