# Really simple question, GCSE Watch

1. On a past paper is the question 'A swimming pool is in the shape of a cuboid and is 60m long, 10m wide and 1.5m deep. How many litres of water does the pool contain?'

How do we know how many litres are in a square meter? Am I to just assume it's 1? I have no mark scheme :/

Sorry if this is a really stupid question...
2. Yes, just multiply all the numbers together.
3. 1 litre = 1000cm3
4. A square metre is just a plane - I think you mean a cubic metre
5. 1 decimeter^3 (10x10x10) = 1 liter
so
1 M^3 = 1000 liters
6. It'd have a volume of 900m^3, converts to 90000cm^3, divide by 1000 (because 1l=1000cm^3) which gives you 90 litres.
