Question

a pile of 500 sheets of paper has a mass of 2kg. The pile is 300mm long, 200mm wide, and 500mm thick. Calculate: 1) The mass of one square meter of paper. 2) The density of the paper. Thank you if you help

Answer 1

Answer:

1 mm , 4 g, 30000 , 60  

Explanation:

(i) Thickness of one sheet = Total thickness of pile/ number of sheets

= 500 mm/500 = 1 mm

(ii) Mass of one sheet = mass of pile / number of sheets

= 2kg/500 = 2000g/500 =4 g (1 kg = 1000 g)

(iii) Volume of the pile = length x width x height

= 300mm x 200mm x 500mm

= 30 cm x 20 cm x 50 cm

= 30000  

(iv) volume of each sheet = Volume of pile/ number of sheets

= 30000/500 = 60  

Answer 2

Answer is 300
