Making equal Weights Measuring CaPaCity

The quantity of a liquid that a container or vessel can hold is called its capacity or volume.

Vessels of different sizes used to measure different quantities of liquid are shown below.

Two 500 g-weights weigh 1 kg. Five 100 g-weights weigh 500 g.
2 × 500 g = 1000 g = 1 kg 5 × 100 g = 500 g

Creative Thinking
Project
Ask your parents how much milk

Two 200 g and one 100 g weights weigh 500 g. Five 200 g-weights weigh 1 kg. 2 L your family consumes in a day. Draw
2 × 200 g + 100 g = 500 g 5 × 200 g = 1000 g = 1 kg 200 500 1 L a beaker and label the amount of
mL mL milk you consume in a day.
