Class: Basic 3

Subject: Mathematics

Topic: Capacity (REVISION)

Content:

The amount of liquid a container holds  is called its CAPACITY.

Liquids  are things like water,milk,kerosene, oil,petrol,juice, water,  etc.

The standard measure for liquid is the litre(l) and millilitre (ml).

Note.—————–

10 millilitre(ml) = 1 centiltre (cl).

10centilitre (cl) = 1 decilitre (dl)

10 decilitre (dl) = 1 litre(l)

1000 litres= (L) = 1 kilolitre (kl)

Note that:

Millilitre = ml

Centilitre = cl

Decilitre = dl

Litre = L

Kilolitre = kl

Examples:

Change to litres and millilitres.

(i) 1200ml = 1000ml + 200ml

Since 1000ml is the same as 1L

Therefore; 1L+ 200ml = 1L 200ml

(ii) 1800ml = 1000ml +800ml

We know that 1000 is equal to 1L

Therefore;  1L + 800ml = 1L 800ml

Class activity 1:

Change to litres and millilitres

(1) 1500ml

(2) 750ml

(3) 4400ml

Examples:

Change to millilitres only

(i) 1L  250ml = 1L+250ml

Since 1L is the same as 1000ml

Therefore;  1000ml + 250ml = 1250ml.

(ii) 3L 150ml = 3L + 150ml

3L = 3 × 1000 = 3000ml

Therefore;  3000ml + 150ml= 3150ml.

Class activity 2:

Change to millilitres only

(4) 8L 330ml

(5) 7L 200ml

(6) 5L 950ml
