If a perfect cube has a width of 2 cm what is the cube volume?
The volume is 8 cubic centimetres.
What is the surface area and volume of a cube with an edge of 3 cm?
well if one edge is 3cm, then that means the length of the cube is 3cm, and because a cube is a 3d square, each side is 3cm which means the volume of the cube is 3x3x3 = 273 AND the surface area us 3x3 for one side x 6 sides = 54cm2 [JxC250: The dimension isn't correct. 27 cubic cm, or cm^3, and 54 square cm, or cm^2.
Why is 2 to the third power call as 2 cubed?
Because, to find the volume of a cube, you raise the length of the side to the third power: if the side of a cube is 2, the volume is 2^3 or 8.
How do you get a side length of a cube with volume?
The volume of a cube is a side cubed. V=S3 So, to find the length of a side, solve for S, to find that the side equals the cube root of the volume. Ex: Volume=8 cubic meters Then 8=S3, therefore s=2 meters.
What is the ratio of surface area to volume?
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.
