A plane is the two-dimensional analogue of a point (zero dimensions), a line (one dimension) and three-dimensional space.
Non-intersecting lines in 3-D space may be parallel but need not be.

Volume has three dimensions - width, height and depth.

It is a geometric model of the physical universe . The three dimensions are length, width, and depth or height
Time is one dimension, not four. If you combine it with space, you can "visualize" it as four dimensions: three dimensions of space, one of time. Sort of visualize it - we can't really visualize four dimensions.
Space is the enormous volume in which matter and energy are located and through which motion takes place. Space is observed to have three dimensions, which are length, width, and depth (or height). It is hypothesized that there may be more dimensions than the three that we observe in our daily lives. String theory gives space ten dimensions and M-theory gives it as many as eleven dimensions including that of time.
There are (so far) three dimensions of space, and one dimension of time.
The four dimensions of Space Time are one real dimension r=ct and three vector dimensions Ix + Jy + Kz. All the dimensions have units of meters. The idea of a dimension of time is an historical artifact.
I assume you mean, "what quantity describes the how much something is extended in three-dimensional space?", in which case the answer is volume.
In any of the three spacial dimensions or a combination of same
Physical objects can only be measured in three dimensions: length, width, and height. These dimensions define the size and shape of objects in space. Any additional dimensions would require advanced mathematical concepts like those found in string theory.
In plane forces, all forces are confined to a two-dimensional plane, while in space forces, forces can act in three dimensions. Plane forces involve only forces in the x and y axes, while space forces can include forces in the z axis as well. Space forces require vector analysis in three dimensions, while plane forces use scalar analysis in two dimensions.
No, not everything in the world exists in three dimensions. For example, time is considered to be the fourth dimension according to some theories, and there are also other concepts like probability or consciousness that may not be easily represented in traditional three-dimensional space.
Cubed. The reason is that space has three dimensions - and that is basically what we are measuring.
In two dimensional space they must. In three (or more) dimensions they need not.
