A tin 10cm long, 7.5cm wide and 2cm deep holds 120g of rice when full.
If 1kg of rice fills a tin 10cm square, find the height of this tin.
~~~~~~~~~~~~~~~~~~~~~~~~~~~
The volume of the 1-st tin is = 10*7.5*2 = 150 cm^3.
The volume of the 2-nd tin is = 10*h cm^3; the height "h" is unknown.
The proportion is

From the proportion, find h
h = = 125 cm. ANSWER
