Well, isn't that a happy little question! To find the surface area of a cube, you simply need to calculate the area of all six sides and add them up. Since all sides of a cube are the same, you can find the area of one side by squaring the length of one side. So, for a 3-inch cube, the surface area would be 6 sides x (3 inches x 3 inches), which equals 54 square inches. Happy painting!

A cube with 2 inch sides is placed on a cube with 3 inch sides then a cube with 1 inch sides is placed on the 2 inch cube what is the surface area of the 3 cube tower?

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.

How do you find the direct proportion between volume and surface area of a cube?

To tackle this you first need to know the equations for both volume and surface area. The surface area of a cube is 6x2 where x is the side length. The volume of the cube is x3. Thus x is the cube root of the volume. We can substitute this in to the surface area equation and say that the surface area of a cube is 6volume2/3 This can also be rearranged to say that the volume of the cube is (the surface area/6)1.5
