The density of \( \mathrm{Cu} \) is \( 8.94 \mathrm{~g} \mathrm{~cm}^{-3} \). The quantity of electricity needed to plate an area \( 10 \mathrm{~cm} \times 10 \mathrm{~cm} \) to a thickness of \( 10^{-2} \mathrm{~cm} \) using \( \mathrm{CuSO}_{4} \) solution would be
(A) \( 13586 \mathrm{C} \)
(B) \( 27172 \mathrm{C} \)
(C) \( 40758 \mathrm{C} \)
(D) \( 20348 \mathrm{C} \)
\( P \)
