Question 105
One cubic meter of aluminium is used to prepare a sheet of 10000 square meters. The thickness (in cm) of the sheet is
Solution
Let thickness = a meters
According to the problem,
a x 10000 m$$^2$$ = 1 m$$^3$$
$$\Rightarrow$$ a x 10000 = 1 m
$$\Rightarrow$$ a x 10000 = 100 cm
$$\Rightarrow$$ a = $$\frac{1}{100}$$ cm
$$\Rightarrow$$ a = 0.01 cm
Hence, the correct answer is Option D
