If "x-x-x" refers to a specific name (like the artist XXXTENTACION ), try searching for the lyrics alongside "2.5 meter."
If x³ = 2.5 m³, what is x?
: Excellent for clear, simple metric conversions (meters to centimeters).
— “x - x - x” equals -x , which would be 2.5 meters only if x = -2.5 m . If you meant something like “X times X times X” (x³) = 2.5 m, then x = cube root of 2.5 ≈ 1.357 m. No video link exists for such a generic phrase.
