To reach at least 360 VA using 180 VA per foot, how many feet are required?

Explanation:
The total VA is found by multiplying the per‑foot rating by the number of feet. With 180 VA per foot, two feet give 180 × 2 = 360 VA, which meets the minimum requirement exactly. One foot only provides 180 VA, not enough, and more than two feet would exceed 360 VA, which isn’t necessary since you only need at least 360 VA.
