THE VOLUME OF A BLOCK OF GOLD IS 0.5CM^3. IF IT IS HAMMARED INTO A SHEET TO COVER THE AREA OF 1 HECTARE, FIND THE THINKNESS OF THE SHEET?

Answer 1

1 hectare = 10^8 cm^2

so, the thickness is

0.5cm^3 / 10^8 cm^2 = ? cm

Answer 2

Thickness of sheet= volume/area =(0.5_/10000)m =(0.5×100×10/10000)mm = 1/20mm = 0.05mm
