Volume

Depths of understanding

1. 1

   Foundation

   You know what volume is, use litres and millilitres, and know that a litre of water is about a kilogram.

   MassThe litre was tied to the kilogram: a litre of water is about one kilogram.
2. 2

   Deeper

   You can find the volume of a box by counting centimetre cubes in layers - length × width × height cubic centimetres - and know that 1,000 cm³ make a litre.

3. 3

   Connected

   You can read a measuring cylinder at eye level from the bottom of the meniscus, and find the volume of an odd-shaped solid from how far the water rises when it goes in, knowing 1 mL = 1 cm³ and 1 m³ = 1,000 L.
