In this activity, we will be answering word problems about capacity.

 

This bucket holds 10 litres of water.

 

 

Example 1

How many buckets are needed to hold 50 litres of water?

10 x ? = 50

 

Answer

One way to find the answer:

1 bucket = 10 litres

2 buckets = 20 litres

3 buckets = 30 litres

4 buckets = 40 litres

5 buckets = 50 litres

 

A quicker way is to  use division to find the answer:

50 ÷ 10 = 5 buckets

 

Example 2

How many litres of water can be held by 3 buckets?

 

 

Answer

Again, 1 bucket = 10 litres

2 buckets = 20 litres

3 buckets = 30 litres

 

It is quicker to use multiplication:

3 × 10 = 30 litres
