Half cubic metre of gold-sheet is extended by hammering so as to cover an area of 1 hectare. Find the thickness of the gold-sheet.
Answers
Given: Volume of gold-sheet = 1/2 m³ or 0.5 m³
To cover an area of the gold-sheet = 1 hectare i.e. 10000 m²
Thickness of gold sheet = (Volume of solid)/(Area of gold sheet)
= 0.5 m³/10000 m²
= 1/20000 m
= (1 × 100)/20000
Thickness of gold sheet = 1/200 cm
[1 m = 100 cm]
Hence, the thickness of the silver sheet is 1/200 cm.
