Question

The volume of a block of gold is 0.5 cu. m if it is hammered into a sheet to cover an area of 1 Hector find the thickness

Answer 1

Area covered by Gold block=1 hectare=10000m^2
Area =length *breadth
So 10000=length*breadth---------(1)
Volume of block=0.5
L*b*h=0.5
10000*h=0.5. ( using equation 1)
h=5/100000
So thickness is equal to 0.00005m
