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
