The volume of a block of a gold is 0.5 m sqare. if it is hammered into a sheet to cover an area of 1 hectare,find the thicness of the sheet.

To find the thickness of the sheet, we need to use the formula for volume:
Volume = Area × Thickness
We are given that the volume of the block of gold is 0.5 m³ (cubic meters) and it is hammered into a sheet to cover an area of 1 hectare.
First, let's convert 1 hectare into square meters:
1 hectare = 10,000 square meters
Now, we can use the formula V = A x T to find the thickness (T) of the gold sheet:
0.5 m³ = 10,000 m² × T
Rearranging the formula to solve for T:
T = 0.5 m³ / 10,000 m²
Calculating:
T = 0.00005 meters
Therefore, the thickness of the gold sheet is 0.00005 meters.
It is not 0.5 meter square
Volume must be in meters CUBED
It is probably a cube.
but from what you wrote I can not say if you mean a cube with a square base with sides of 0.5 meter
In which case we would have V = .5^3 = .125 m^3
or
perhaps you mean V = 0.5 m^3
in either case
V = thickness times one hectare
but 1 hectare = 10,000 m^2
so
V /10,000 = thickness in meters
(which will be extremely small)
