t=\frac{k}{w}
where t is the required time to complete the project, k is a constant of proportionality, and w is the number of workers.
Plugging the given values into the equation, we get:
24=\frac{k}{5}
which gives k = 120.
If the required time to complete the project is 15 days, the equation becomes:
15=\frac{120}{w}
Solving for w, gives w = 120/15 = 8 workers.

Answer: the cube root of 512 is 8.

Step-by-step explanation:

First divide 512 and take the least factors as I have shown,

512= 2×2×2×2×2×2×2×2×2

Now, make the triple twins of these factors,

(2×2×2)(2×2×2)(2×2×2)

Now, take one number from each pair and multiply them,

2×2×2=8

Therefore, the answer of the cube root of 512 is 8.
