Would this workings and answer be correct? Also the final part I am stuck on.

Cylinder is 90cm3

Cone is 15cm3

Add them together to get 105cm3

1 litre = 1000cm

So there is 20,000 cm3 of candle wax

Divide the 20,000 into 105cm3 this is where I am stuck. When I put 20,000/105 into the calculator I get a number that is way too big.

Am I putting it in wrong or making some other mistake? Thanks.
 
Are you using 3 for pi?

What is the formula for the volume of a cone?
What is the formula for the volume of a cylinder?

If you are truly dividing 20,000 into 105, then that is 105/20,000 NOT 20,000/105!
