6a^2

a = side lengths

let a=2 units, each side area of cube = 2 units^2 (4 sq. units), total sides = 6, total area = 6 x 4 sq. units (24 sq. units).

A cube has six surface areas, all of which are squares of the same size, so you just take the area of one of those squares and multiply the result by 6.

How to find the surface area of a cube?

Surface Area of a Cube = 6 a 2(a is the length of the side of each edge of the cube)In words, the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a, or a 2 . Since these are all the same, you can multiply one of them by six, so the surface area of a cube is 6 times one of the sides squared.


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
