Identify total tape: Step $1$ : Identify total tape needed and tape per roll. $\newline$ Total tape needed = $8,000$ cm, Tape per roll = $2,000$ cm. $\newline$ We need to divide the total tape needed by the tape per roll to find out how many rolls are needed. $\newline$ Calculation: $8,000 \div 2,000 = 4$ .
