A matchbox has a mass of 20 g. The mass of the match box alone is 8 g. If there are 6 matches in the box,what is the mass of each box?

Answers

Hence mass of 6 matches is  6 gm

What is mass?

Anything that occupies space is said to have acquired mass. That means quantitative measure of inertia, a fundamental property of all matter.

How to solve?

Given mass of 1 match box=20g

Mass of match box alone = 8 g

Mass of  match box if it has 6 matches= 20-8(weight of matches)

If box has 20 matches in all 1 match will have mass of 1 gm then 6 matches will have mass of 6 matches.

#SPJ2
Each match has a mass of 2 g. This is because you must take the matchbox's total mass and subtract the mass of the box alone. You get 12, and then you divide by 6 to find the amount of each match
