Depending on the shape of the 3D object, you need additional dimensions like diameter or width and height besides the length, in order to calculate the volume.
yes
You can't tell the dimensions of a rectangle from its area, or the dimensions of a prism from its volume.
Volume = length X width X height. Therefore, take the cube root of the volume to find all the dimensions
you look at the shape
You multiply all three dimensions. This only applies for prisms. For example, for a prism with sides 3, 5, and 9, you multiply the dimensions (3*5*9) = 135 units cubed.

yes
A ruler is used to measure length and does not account for the height or width of an object, which are necessary to calculate its volume. To find the volume of a paperclip, you need to measure its dimensions in three dimensions using a tool such as a caliper or by using a water displacement method.

Well in general, you can find volume if you have the relevant dimensions. It's much easier for simple shapes. For complicated shapes, it's easier to use other methods. Immersing an irregularly shaped object in a graduated cylinder is a very useful method of finding volume.

Three dimensions are required for volume
Yes. You can find the dimensions of the object (Assuming the dimensions are measurable) and calculate its volume in centimeters cubed.
Just knowing the volume in centimeters cubed of a rectangular prism would not allow you to find the dimensions.
To calculate the volume of a rectangle, you must multiply the length, the width, and the height--so the volume depends on the dimensions.
