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 to calculate the number of rolls required. $\newline$ Total amount of electrical tape needed: $8,000 \, \text{cm}$ $\newline$ Amount of tape on each roll: $2,000 \, \text{cm}$ $\newline$ To find the number of rolls, we divide the total amount of tape needed by the amount of tape on each roll. $\newline$ Calculation: $8,000 \, \text{cm} \div 2,000 \, \text{cm}$
Find Number of Rolls: Perform the division to find the number of rolls. $\newline$ $8,000\,\text{cm} \div 2,000\,\text{cm} = 4$ $\newline$ So, the electrician needs to order $4$ rolls of tape.
