Question

Accuracy in the measurement of the volume in cubic meter should be near to..

Answer 1

Volume is the amount of space occupied by an object or substance. It is one of the derived quantities defined by the International system of Units. The unit of volume is the cubic metre (m3). This is what is called a coherent derived unit of quantity because it is expressed purely in terms of one of the base units defined by the International system of Units, namely length. Whereas length has the metre (m) as its unit, volume has the cubic metre. In fact, for a number of basic three-dimensional shapes, we can find the volume of an object quite easily simply by measuring its dimensions, in whatever unit of length is appropriate (e.g. metres, centimetres or millimetres) and then applying the correct formula to those measurements to determine its volume. The simplest possible example is probably the cube, which by definition has the same length in all three dimensions. If we had a cube-shaped object for which each side measured two metres (2 m) for example, the volume would be 2 × 2 × 2 cubic metres, which would give us eight cubic metres (8 m3). The formulae for a number of common three-dimensional shapes are given in the following table.
