Identify total tape needed: Step $1$ : Identify the total amount of tape needed and the amount per roll. $\newline$ Total tape needed = $8,000 \, \text{cm}$ , Tape per roll = $2,000 \, \text{cm}$ . $\newline$ Calculate the number of rolls by dividing the total tape needed by the tape per roll. $\newline$ $8,000 \, \text{cm} \div 2,000 \, \text{cm} = 4$ rolls.
