surface area of cube=6*side*side =6*7.2*7.2
When asked to work out the lengths of its edges and its surface area.
There are 6 faces to a cube. So work out the area of one face and multiply by 6. For a 6 inch cube: 6 x 6 = 36 x 6 = 216in3.
Area of a cube = 6 X side X side since all sides of cube are equal.
Work it backwards.-- A cube has 6 faces.-- The area of each face is (150 / 6).-- The length of each side is sqrt(150/6).-- The volume of the cube is (side)3 = (150/6)3/2 = 125 cubic units

Yes, that's exactly right. Great work !
An example of surface area to volume ratio can be seen in cells. As cells grow larger, their volume increases at a faster rate than their surface area. This can lead to limitations in nutrient or waste exchange, as the surface area may not be sufficient to support the volume of the cell. This is why cells tend to have a small size to maintain an efficient surface area to volume ratio for necessary exchanges.
If you are referring to a cube with 15mm sides then this is how you would work it out. A cube has 12 edges of the same length, and 6 faces of the same area. We know area is length^2 (length to the power of 2 / length X length. What you have to find is the total surface areo of all of the faces. If you can work out the area of one face you will know the area of the others. Since the area of one face is the area of one square, we can use the fomula length^2 which is also known as length X length. we also know in this instance the length of the square is 15mm. so we substitute 15 into the formula length X length: 15 X 15 =225 Square mm (we write square millimetres as we are refering to area [2 dimensions] But we have so far only worked out the area of one face. since there are 6 faces on a cube we multiply the area of one face by 6. So in this Case: 225 square mm X 6 =1350 square mm that is how you find the surface area of any cube.
It would help if the question was less obscure. What do you mean by "work"? How the surface area affects chemical processes (for example the surface area of catalysts), or diffusion, or surface areas and friction?
The surface area of one face is one side squared. There are six faces. Six times the square of one side.
A quadrilateral does not have a surface area because it is not a voluminous figure.
Work out the surface area of its 6 faces individually and then add them together
