Question

Why 1ml is equal to 1cm3?

Answer 1

Hey,
Ur answer is here,
As We know that volume is equal to the space created.The term cubic centimeter is 1cm long and 1cm high.One milliliter (mL) is the equivalent volume of a cubic centimeter. Therefore the term mL is preferred over centimeter cube.

Also we can obtain it from the relation,

1 litre = 1000 cm3

and also 1 litre=1000mL

Then 1000mL=1000 cm3

or 1 cm3 = 1 mL
Hope it helps you ☺️

Answer 2

A nice question which i will explain using an activity.

Let us take a cube of size a=1 cm {length=breadth=height=a=1cm}

Note-We can take any other 3D figure but we have to take specific dimensions to make a volume of 1cm³. Cube is the simplest figure so I am considering that.

Also the cube we are taking has negligible thickness means 0 thickness.

This is because thickness is inversely proportional to volume means the increase in thickness will decrease the volume.

Volume of cube = a³ i.e 13=1cm³

Take a measuring container and pour water till the measure of 1 ml.

Now pour this water in cube

Now we will observe that the water is at the brim and no more water can be stored .

Therefore 1cm³=1ml

We equate volume to quantity because as volume is simply the space inside the object and quantity occupies this space .Therefore they are equated.
