# Find The Value of The Equation

If x = 5, y = 6 and z = -11 then the value of x^{3 }+ y^{3} + z^{3} is

- -890
- -970
- -870
- -990

**Answer: (4) – 990**

**Explanation:-**

X = 5 , Y = 6 , Z = – 11

The value of X^{3} + Y^{3} + Z^{3} = 5^{3} + 6^{3} + (- 11)^{3
} = 5 x 5 x 5 + 6 x 6 x 6 + (-11) x (-11) x (-11)

= 125 + 216 – 1331

= 341 – 1331 = – 990

Hence, the answer is (4) – 990.
