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
