Calculate Total Tape: First, we need to determine the total amount of electrical tape the electrician needs and the amount of tape on each roll. $\newline$ Total amount of electrical tape needed: $8,000\,\text{cm}$ $\newline$ Amount of tape on each roll: $2,000\,\text{cm}$ $\newline$ To find out how many rolls the electrician should order, we divide the total amount of tape needed by the amount of tape on each roll.
Determine Rolls Needed: Now, we perform the division: $\newline$ $8,000\,\text{cm} \div 2,000\,\text{cm}$ per roll = $4$ rolls $\newline$ This calculation tells us the number of rolls the electrician needs to order.
