| How
is volume measured? (Continued)
Answer:
If you said 1 million, you were right! Excellent!
But can you show how you got the answer?
1
centimeter = 1 meter Therefore:
100 centimeters = 1 meter
100 Or
1
meter = 100 centimeters
Then,
1
cubic meter = 100 cm x 100 cm x 100 cm
= (100) x (100) x (100) cm x cm x cm
= 1,000,000 cm³
For objects
that have unusual shapes, volume must be measured in another way.
Take the human body, for instance. We all have different shapes,
so there is no formula we can use to measure our volume!
But there is
another way we can measure volume which is by
immersion
in water. If we have a container
with a known volume of water in it, we can submerge an object in
the water and then record the new level of the water. Next,
we subtract the original volume from the final volume and we are
left with the volume of the object!
Volume
of an irregular object = final volume (water + object) - initial
volume (water only)
