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) $$\ \ 6a^2 - 21\pi b^2$$
