Answer:
[tex]A = 7.5 \times 10^6 m^2[/tex]
Explanation:
Since volume of all the liquid is always conserved
so here we know that
[tex]V_{total} = N V[/tex]
[tex]25 cm^3 = N(\frac{4}{3}\pir^3)[/tex]
[tex]25 = N (\frac{4}{3} \pi (1.0 \times 10^{-5})^3)[/tex]
[tex]N = 5.97 \times 10^{15}[/tex]
now we know that total surface area is given as
[tex]A = N(4\pi r^2)[/tex]
[tex]A = (5.97 \times 10^{15})(4\pi (1 \times 10^{-5})^2[/tex]
[tex]A = 7.5 \times 10^6 m^2[/tex]
