There is no volume that has units of length. If you meant to write 8cm3 then the cube has all edges 2cm (ie the "cube root" of 8 times the "cube root" of cm3)
Well, darling, a 1-inch cube has a volume of 1 cubic inch. It's as simple as that. So, if you ever need to fill a tiny cube with some liquid courage, you'll know exactly how much it can hold.

You cannot weigh an area, but you can weigh a volume... so, one cubic meter of stainless steel weighs 7480 - 8000 kg. See related link for the source.
The volume of the sphere is proportional to the cube of its radius.Increasing the radius by 5% causes the volume to increase by the factor of (1.05)3= (1.05 x 1.05 x 1.05) = 1.157625= 15.7625% increase in volume.(Regardless of what the radius and volume were before the increase.)
Weight is related to an objects mass and acceleration due to gravity not its volume.
A 1.5 cubed cube of tungsten would have a volume of 3.375 cubic inches (1.5 x 1.5 x 1.5). Tungsten has a density of 0.69 lbs/in3, so the weight of the cube would be approximately 2.33 pounds (3.375 x 0.69).
Different techniques are used for different shapes. The volume of a cube is simply the edge of the cube, cubed (i.e., taken to the third power). The volume of a sphere is 4/3 pi times the radius cubed. The volume of an irregular shape requires the use of integral calculus. Everything can be calculated but some calculations are much more complicated than others.
First cube's edge is 4 units, volume is 64 cunits. Second cube's edge is 12 units, volume is 1728 cunits, an increase of 27 times the original. This is to be expected as 3 cubed is 27.
Try it out. A cube with four-inch sides has a volume of 64 cubic inches. A cube with two-inch sides has a volume of 8 cubic inches. That's eight times less.
The volume would be 27 times greater as 3 cubed is 27 times greater than 1 cubed, the volume would therefore be 27 centimetres cubed. 1x1x1=1 3x3x3=27
To calculate the volume of a cube, you use the third power of the length, so for example, if the length of an edge of a cube is 3" then the volume is 3x3x3 = 27 cubic inches. As a result, any time a number is raised to the third power, we can call it cubed, much as raising it to the second power is that number squared.
1ft3 of what?
The volume of an object is (for most intents and purposes) the amount of space it takes up. For example, a cube with side lengths all equal to 1cm will have a volume of 1cm3. The mass of an object is how much it weighs, which varies depending on the density of the object. A cube made of lead will weigh significantly more than a cube made of plastic, and hence have much higher mass, though their volumes might be identical.
