Please note, that:
The solids in question have various volumes because a different number of identical cubic blocks was used to make them.
The figures have the same volumevolumevolume when they are made of the same number of identical cubes.

The volumevolumevolume of spatial figures can be measured by using identical cubes.
One of the basic unit of volumeunit of volumeunit of volume is the volume of the cubevolume of the cubevolume of the cube with the edge of 1 cm. It is one cubic centimetrecubic centimetrecubic centimetre, which is written down as 1 cmIndeks górny 33.
