Question

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. Sollution the qestion

Answer 1

let sheet dimensions are
length = l m
breadth = b m
thickness = h m
area of the sheet = lb = 1 hectare=10000 square m
volume of the sheet = volume of the gold block
(lb)h= 0.5m^3
10000*h = 0.5m^3
h = 0.5/10000 m^3
h= 5*(10)-5 m^3
or
h= 0.00005m^3

Answer 2

Given,
volume  of golden block = 0.5m³
area of the sheet = 1
            1 hectare = 10000
the thickness of the sheet = volume /area
                                          =0.5 / 10000
                                          =0.00005m
