Answer:
Brian weighs 79,491 kilograms.
Step-by-step explanation:
Given that Brian weighs 4.2 times more than a 5 gallon bucket of water, to determine Brian's weight measured in units of weight, it comes from the following calculation:
1 liter of water = 1 kilo
1 liter of water = 0.26418 gallons
1 kilo = 0.26418 gallons
5 x 4.2 = 21
0.26418 = 1
21 = X
(21 x 1) / 0.26418 = X
79,491 = X
Therefore, Brian weighs 79,491 kilograms.
