Video Summary

The chocolate bar initially has a grid of squares. Neil eats a 2-square-wide strip consisting of 12 squares, making it 6 squares long. Jack then eats a 1-square-wide strip consisting of 9 squares. After these portions are removed, the task is to determine the remaining number of squares. By visually piecing the bar back together and accounting for the removed portions, the remaining chocolate squares are found. The dimensions of the remaining bar are calculated as 5 by 9. Multiplying these gives the answer of 45 squares left in the chocolate bar.
