A white die has gray dots. If the area of each of the die's faces is \(a\) and the area of each of the die's dots is \(b,\) what is the area of the white surface on the die in terms of \(a\) and \(b?\)
(A) \(\ \ 4a-21b\)
(B) \(\ \ 6a - 6b\)
(C) \(\ \ 6a-21b\)
(D) \(\ \ 4a^2 - 21\pi b\)
(E) \(\ \ 6a^2 - 21\pi b^2\)
