The cube's surface area consists of six squares; you can simply add the area of each of the squares. Note that each of the squares has the same size.
When you change the linear size it changes the areas by the square and the volume of the cube.
The surface-area-to-volume ratio also called the surface-to-volume ratio and variously denoted sa/volor SA:V, is the amount of surface area per unit volume of an object or collection of objects. The surface-area-to-volume ratio is measured in units of inverse distance. A cube with sides of length a will have a surface area of 6a2 and a volume of a3. The surface to volume ratio for a cube is thus shown as .For a given shape, SA:V is inversely proportional to size. A cube 2 m on a side has a ratio of 3 m−1, half that of a cube 1 m on a side. On the converse, preserving SA:V as size increases requires changing to a less compact shape.
This Wikipedia passage should be able to help you out. Note that this is just a cube and other shapes such as spheres will have a different ratio.(From Wikipedia "Surface Area to Volume Ratio")The surface-area-to-volume ratio has physical dimension L−1 (inverse length) and is therefore expressed in units of inverse distance. As an example, a cube with sides of length 1 cm will have a surface area of 6 cm2 and a volume of 1 cm3. The surface to volume ratio for this cube is thus{\displaystyle {\mbox{SA:V}}={\frac {6~{\mbox{cm}}^{2}}{1~{\mbox{cm}}^{3=6~{\mbox{cm}}^{-1}}. For a given shape, SA:V is inversely proportional to size. A cube 2 cm on a side has a ratio of 3 cm−1, half that of a cube 1 cm on a side. Conversely, preserving SA:V as size increases requires changing to a less compact shape.
If they are all the same size, the surface area is just the total surface area, which is 6 (faces) x edge x edge - that is the area of one face, (the length of one edge times itself as cubes have square faces) x the number of faces (6) x the number of cubes (3). Then subtract fom this the area not exposed, which is the top face of the bottom cube, top and bottom of the middle cube and bottom face of the top cube - so that's 4 faces. So the formula boils down to: 6 x 3 x edge x edge - 4 x edge x edge ... or ... 14 edge² If they are different sizes: 1. Work out the total area of each cube. 2. Between the bottom and middle cube, take the smaller and that face is hidden on both cubes, so subtract twice this face. 3. Do the same for the top and middle cubes.
Surface area also decreases
The cube 3 cm on a side has the greater surface area.
The Bigger Cube?
The cube's surface area consists of six squares; you can simply add the area of each of the squares. Note that each of the squares has the same size.
starting size n, surface area = 6 x n2; starting size 2n surface area 6 x 4n2 so surface area would be quadrupled.
Suppose the cube has edges of length x. Then the area of each face (side) is x2. There are six faces so the total surface area is 6x2. The volume of the cube is x3. So 6x2 = x3 DIviding both sides by x2 gives x = 6.
When you change the linear size it changes the areas by the square and the volume of the cube.

shape/size/surface area of the ice cube also the time it is in and the heat settings i think?
Ok, say you have a large cube with edges of one inch each. If you cut that cube into eight separate cubes, each with a side length of .5 inches, the surface area is increased, because now more of the original substance is exposed.
If you mean a cube, it is bounded by 6 squares, each of the same size. Therefore, you just multiply the area of one of the squares by 6.
The smaller a cell is, the greater the ration of Surface Area to Volume. As the cell size increases, the ratio of surface area to volume decreases. Volume will increase rapidly while surface area increases slowly. Cells must maintain a balance between surface area and volume because the amount of surface area determines how much food it can take in and how much waste it can remove. The greater the surface area, the longer it can survive.
