# Length $L$, area $A$ & volume $V$

Size properties that cover a portion of space in 1, 2 and 3 dimensions. Length is the space straight between two positions. Sweep out the space from each point along a length to have area. Sweep out the space from each point of an area to have volume.

• Scalar properties derived from position
• Symbols: $L$, $A$ and $V$
• SI-units: metre $\mathrm m$, square metre $\mathrm m^2$ and cubic metre $\mathrm m^3$
