3√1000 = 10
because 10 • 10 • 10 = 1000
3√8 = 2

10+2 = 12
It's not plus or minus because it's a cube root rather than a square root.
X=time of the third person it would take to fill the pool
We can suggest this equation:
6[(1/20) + (1/15) +(1/x)]=1
6[(3x+4x+60)/60x]=1
(7x+60)/10x=1
7x+60=10x
7x-10x=-60
-3x=-60
x=-60/-3
x=20
Answer: the third person alone would fill the pool in 20 hours .
