  1. Identify Total Tape: Identify the total amount of tape needed and the amount per roll.\newlineTotal tape needed = 8,000 cm8,000\,\text{cm}, Tape per roll = 2,000 cm2,000\,\text{cm}.\newlineWe need to divide the total amount by the amount per roll to find the number of rolls.\newlineCalculation: 8,000÷2,000=48,000 \div 2,000 = 4.
