The quadratic looks good. Though a=1 where you list a, b and c.
Oh

Can you explain conversions please?

Which ones specifically do you need help with?

Do you know how many cm are in a metre? Do you know how many millilitres are in a litre?

Not really. Need to learn them.

Distances increase by powers of 10:
10mm = 1cm
100cm = 1m
1000m = 1km
10ml (mililitres) = 1cl (centilitres)
10cl = 1dl (decilitre)
10dl = 1L (litre) = 1000ml (I think you only need to know that 1 Litre = 1000ml for GCSE)
From there you can just convert between any two by means of multiplication by a common factor on both sides. E.g. 2000m = 1000 x 2 therefore in km it must be 1 x 2 = 2km.

The basic ones you should know are:
1 cm = 10 mm
1 m = 100 cm = 1000 mm
1 km = 1000 m
Btw a kilo is 1000 and centi literally means 100
Also 1 cm^3 is 1 ml
1 l = 100 cl = 1000ml

10mm = 1cm
100cm = 1m
1000m = 1km
Weights and measurements do not and instead follow this pattern:
10ml (mililitres) = 1cl (centilitres)
10cl = 1dl (decilitre)
10dl = 1L (litre) = 1000ml (I think you only need to know that 1 Litre = 1000ml for GCSE)
From there you can just convert between any two by means of multiplication by a common factor on both sides. E.g. 2000m = 1000 x 2 therefore in km it must be 1 x 2 = 2km.

Thank you will memorise this.

I'm just wondering how they don't follow the same pattern because there is such thing as decimetre and what you said about distances increase by power of ten is the same as for litres and stuff

Yeah I'm not sure why I said. I meant to say that they don't grow as fast (if that makes sense).

Do I do the other questions in the same way?

Yep

Yep
Help on question 4 please.
Do I find the volume first?

Original post by z_o_e
Yep. Use the conversion of 1ml=1cm3 for this one.

I done this so far
