Answer:
50
Explanation:
To determine the total number of kilograms from 15 boxes, we need to know the weight of one box. Let's assume that one box contains 50 sachets (this is just an assumption, the actual number may vary). Then the weight of one sachet is 4 grams or 0.004 kilograms.
the weight of one box is:
50 sachets x 0.004 kg/sachet = 0.2 kg
the total weight of 15 boxes is:
15 boxes x 0.2 kg/box = 3 kg
the total weight of 15 boxes is 3 kilograms.
to determine whether the 15 boxes will be enough to last for a year, we need to know how many sachets a person uses in a day. Let's assume that a person uses one sachet per day.
then the total number of sachets used in a year is:
1 sachet/day x 365 days = 365 sachets
the total number of sachets in 15 boxes is:
15 boxes x 50 sachets/box = 750 sachets
since 750 sachets is greater than 365 sachets, 15 boxes will be enough to last for a year.
to determine the number of sachets that will make one box, we need to know the weight of one box and the weight of one sachet. Let's assume that one box weighs 0.2 kg and one sachet weighs 4 grams or 0.004 kg.
then the number of sachets in one box is:
number of sachets = weight of box / weight of one sachet
number of sachets = 0.2 kg / 0.004 kg
number of sachets = 50 sachets
therefore, one box contains 50 sachets.
