Explanation:

Step1: Recall metric - mass conversion

1 kilogram = 1000 grams. So to convert kilograms to grams, we multiply by 1000.

Step2: Recall time - unit conversion

1 hour = 60 minutes and 1 minute = 60 seconds. So 1 hour=60×60 = 3600 seconds. To convert 3 hours to seconds, we do 3×3600=10800 seconds.

Step3: Recall metric - mass equivalence

1000 grams is equal to 1 kilogram. This is a fundamental metric - system conversion.

Answer:

Question 43: A. 1000
Question 44: A. 10800 seconds
Question 45: True
