Shape & Space 2D - Characteristics

Like 3D Shapes, each 2D Shape also have their own characteristics.

The characteristics of each 2D shape are shown below:







































Other interesting characteristics of the 2D Shapes are:


















That is all for 2D Shapes. Thank you.

Volume Of Liquid - Applying Volume

Similar to Mass and Length, Volume also have its units too.


The most common units are: Litre (L) and Millilitre (mL)

1 Litre (L) = 1000 Millilitres (mL)


In the picture below, there are 5 bottles.


The volume of Bottle 1 = 15 ml


The volume of Bottle 2 = 30 ml

The volume of Bottle 3 = 60 ml
The volume of Bottle 4 = 125 ml


The volume of Bottle 5 = 200 ml

Here are a few questions:
Q1) The volume of Bottle 3 is 60 ml. How many Bottles 1 are needed to achieve the same volume as Bottle 3?

Answer:
Bottle 3 = Bottle 1 X ?
60 ml = 15 ml + 15 ml + 15 ml + 15 ml

So, 4 Bottles 1 are needed to achieve the same volume as Bottle 3.

Q2) How many Bottles 5 are needed to achieve 1.2 Litres (l) ? [Note: 1 L = 1000 mL]

Answer:
Bottle 5 = 200 ml
1.2 L = 1200 ml

1200 ml = 200 ml + 200 ml + 200 ml + 200 ml + 200 ml + 200 ml

So, 6 Bottles 5 are needed to achieve 1.2 Litres.


Observe the picture below:

Label the volume of liquid for all the bottles (Green Bottle, Yellow Bottle, Red Bottle and Blue Bottle)

Answer:
Green Bottle = 400 ml
Yellow Bottle = 250 ml
Red Bottle = 1.5 l
Blue Bottle = 1 l

Thank you.
