Introduction
</span>
<br />
<br />
To get the water fro the rain, we use different forms of tanks or containers. We need to know the amount of each container or tank. The capacity can be: 2000 litres or
<br />
2 000dm
<sup>
3
</sup>
equals 2,5 000 litres or 5 000dm
<sup>
3
</sup>
equals 5m
<sup>

</sup>
.
<br />
<br />
We can also use measurements to know the volume o firewood.
<br />
<br />
In this mileston, we will learn how to use the measurment of volume and firewood, comparing with measurement of the capacity nd mass.
<br />
<br />
To know the capacity of tank we hve to identify its height and the are of the base(bse are)
<br />
<br />
For example:
</p>
<ul>
<li>
A cube has 5m as height and each side of his base is 5m
</li>
</ul>
<p>
The volume will be:
<br />
<br />
V=H*S*S=5m*5m*5m
<br />
25m
<sup>

</sup>
*5m
<br />
Volume =125m
<sup>

</sup>
, tthis volume is the same of a pea of firewood of the same dimensionn but we count itin steres(125steres)
