The volume of a block of gold is 0.5 m3. If it is hammered into a sheet to cover an area of 1 hectare, find the thickness of the sheet.
It is given that,
Volume of the block = 0.5 m3
We know that,
1 hectare = 10000 m2
Therefore,
Thickness of the sheet = volume/area
= 0.5/10000
= 0.00005 m
= 0.005 cm
= 0.05 mm
