i dont think 1 metre cube = a litre

24a) P(1+r)

r = 0.0475/12

p=24000

r= 36

24000(1+0.0475/12)^36

= $27667.89

23d) v= pie x r squared x h
pie x 25 x 7.8
= 613

8 x 612.61 = 4900.88mL
=4.9 L
does have racing requirements becuase is under 5 litres

hope dat helps

For capacity, the best two things to remember are:
1 cm3 = 1 mL
1 m3 = 1 kL

It's then pretty easy to convert to litres (L) cause you just multiply by 1000 (from kL) or divide by 1000 (from mL), depending on the units you have.
