To solve for $a^3 + b^3 + c^3$ given the following conditions:

1. $a + b + c = 10$
2. $a^2 + b^2 + c^2 = 50$
3. $abc = 9$

We can use the identity: $a^3 + b^3 + c^3 - 3abc = (a + b + c)(a^2 + b^2 + c^2 - ab - bc - ca)$

We know that: $a^3 + b^3 + c^3 = (a + b + c)(a^2 + b^2 + c^2 - ab - bc - ca) + 3abc$

First, calculate $ab + bc + ca$ using the identity: $(a + b + c)^2 = a^2 + b^2 + c^2 + 2(ab + bc + ca)$ Substitute the known values: $10^2 = 50 + 2(ab + bc + ca)$ $100 = 50 + 2(ab + bc + ca)$ $50 = 2(ab + bc + ca)$ $ab + bc + ca = 25$

Now we can substitute into our main equation: $a^3 + b^3 + c^3 = (10)(50 - 25) + 3 \times 9$ $a^3 + b^3 + c^3 = 10 \times 25 + 27$ $a^3 + b^3 + c^3 = 250 + 27$ $a^3 + b^3 + c^3 = 277$

Thus, the value of $a^3 + b^3 + c^3$ is 277.
