Final answer:
To find out how many 5.8 cm rods can be cut from a 500 cm long metal pole, divide the total length of the pole by the length of each rod. In this case, 500 cm divided by 5.8 cm equals approximately 86.2, which rounds down to 86 rods.
Step-by-step explanation:
To determine how many rods of 5.8 cm each can be cut from a metal pole that is 500 cm long, you would take the length of the metal pole and divide it by the length of each rod:
Total number of rods = Length of the metal pole ÷ Length of each rod
Total number of rods = 500 cm ÷ 5.8 cm
Total number of rods = approximately 86.2
Since you can't have a fraction of a rod, you would round down to the nearest whole number. Therefore, the answer to how many 5.8 cm rods can be made from a 500 cm pole is 86 rods (option b).
