Question 32

2190 diapers will be needed in a year.

To determine the number of diapers needed in a year, we multiply the number of changes per day by the number of days in a year. With a caregiver changing their baby 6 times a day, the calculation is 6 changes/day × 365 days/year, which equals 2190 diapers.

A) 2160 diapers

Option A is incorrect as it represents a slight underestimation of the total number of diapers needed. The calculation of 6 changes per day multiplied by 360 days results in 2160, which does not account for the full year of 365 days.

B) 2100 diapers

Option B is also incorrect because it significantly undercounts the total required diapers. This choice suggests an incorrect multiplication or misunderstanding of the daily changes, as 2100 diapers would only be accurate if the frequency of changes or the time frame was miscalculated.

C) 2190 diapers

Option C is correct. It accurately reflects the total number of diapers needed for a year based on the calculation of 6 changes per day for 365 days, confirming that 6 x 365 equals 2190.

D) 6000 diapers

Option D is incorrect because it vastly overestimates the number of diapers needed. This figure may stem from a misunderstanding of the frequency of changes, as it would imply changing the baby significantly more than 6 times a day throughout the entire year.

Conclusion

The calculation of 6 diaper changes per day for a full year confirms that 2190 diapers are necessary, validating Option C as the correct answer. The other options either underestimate or overestimate the required quantity based on the given daily change frequency, demonstrating a clear reasoning flaw in their calculations.
