Mass - Applying Mass

In previous entry, you have learned about Mass. Do you know we have units to measure Mass?

The basic unit for Mass is gram (g):

1 kilogram (kg) = 1000 gram (g)


There are many equipments to measure Mass. Some of these equipments are:

(Weight Balance)

(Triple Beam Balance)

 (Mechanical Scale)






Now, if a book is weighted at 50 grams while a brick is weighted at 200 grams. How many books are needed so that the weight is the same as a brick?

Solution:
1 Brick = 200 g
1 book = 50 g

50 g X ? = 200 g

50 g + 50 g + 50 g + 50 g = 200 g

So, it becomes:

50 g X 4 = 200 g

Answer:
4 books are needed to weight the same as a brick.


That's all for today. Thank you.
