Ω=int_0^1(root(3)(x)-x^2)dx=

int_0^1root(3)(x)dx-int_0^1x^2dx=

int_0^1x^(1/3)dx-int_0^1x^2dx=

[3/4x^(4/3)]_0^1-[x^3/3]_0^1

3/4-1/3=5/12m^2

5/12

Explanation:

the integral is the area between the blue and red curves from the green line (x=0) and the orange line (x=1):

the area is int_0^1(x^(1/3)-x^2)dx (subtract x^2 from x^(1/3) because x^(1/3) is always greater on 0<x<1)

solving:
int_0^1(x^(1/3)-x^2)dx=F(1)-F(0), where F(x)=3/4x^(4/3)-1/3x^3

=3/4(1)^(4/3)-1/3(1)^3-3/4(0)^(4/3)+1/3(0)^3
=3/4-1/3=5/12
