the surface area is the sum of all the areas of all the shapes that cover the surface of the object
the surface of a cube is the number of surface multiply by the surface of a part.
As all are identical, this is 6
and for one surface is the surface of a rectangle with both sides that are equal so a²
The result is 6 a²

well... there are 6 surface in a cube. and how to get the are of each surface is s squared. We know that surface area is the sum total area of the surface. And a cube is just like a square so their sides are equal. So the formula is SA=6s squared. s represents sides.

length squared ( that is the surface area of 1 side) times by 6 ( there are 6 sides to a cube)

A cube has 6 surfaces in all, all of which are squares. The 6 squares each are of same size (length of side is equal)
Thus, the total surface area = 6* area of square = 6* suare of side

Surface area of a cube= (lengthxwidth)x6
It's just 6 squares. Find the area of one square, and multiply by 6 faces.

If you know some calculus then this may be useful to you.
the cube or any closed surface certain volume related with its surface area.
Keep in mind whenever relation word comes in do expect Calculus to be around somewhere,
V = a^3
Surface Area would be 3a^2

A cube has six faces. All of them are squares.
So, the area of one face =l x l (length of one side)
so, the area of six faces = l^2 x 6
