Thankyou for your reply it was very helpful I am still struggling with integrating x=(y/2)^1/3 as I do not know what to do when bringing the power down as the 2 is already there each method I try give me the wrong answer

For part 2,

integrating this, we bring out the denominator under y first, then raise the power of y by 1

and divide by the new power

evaluated from y=0 to y=54

from 0 to 54
