sir can't i use the limits while finding velocity and then equate to dx/dt? then it is 165m.

sir i think sir you have by mistake taken 3^3 as 9 it should be 27 isn't it??

Ans 1 ->

He is right as the equation was 4/3 (t)^3 when you substitute t = 3 we get 4/3 *(3^3) = 27 .

Ans 2 ->

sir took 3^3 as 27,but also it was to be divided by 3.so, 27/3 = 9
