Explanation

We need to find ? in (215.98)^(1/3) × √120.6 - ? = 35% × 698. Rearranging: ? = (215.98)^(1/3) × √120.6 - 35% × 698. Approximating: ³√216 = 6 (since 6³ = 216). √121 = 11 (since 11² = 121). 35% × 700 = 0.35 × 700 = 245. So ? ≈ 6 × 11 - 245 = 66 - 245 = -179. This matches option B. The calculation is straightforward with proper approximations.
