The length of a piece of timber is measured to be 17.43m using a ruler. What is the upper bound of the largest possible length of this rope when rounding?

Answer 1

The largest possible length of the timber when rounding would be when rounding down, as this would give us the smallest possible value.

When rounding down a number with two decimal places, we ignore the numbers after the second decimal place. Therefore, the rounded down length of the timber would be 17.40m.

Since we want to find the upper bound of the largest possible length, we should round up to the nearest whole number. Therefore, the upper bound of the largest possible length of this rope when rounding is 18 meters.
