4.918 quarters approx.

Explanation:

(Volume of paper / Volume of quarter ) gives the number of quarters.

Volume of paper #V_p = l_p * b_p * h_p = 10.5 * 8 * 0.0025 = 0.21# cu. in.

Volume of quarter #V_q = pi r_q^2 h_q = pi * (0.9375/2)^2 * 0.0625 ~~ 0.0427# cu. in.

No. of quarters = #V_p / V_q = 0.21 / 0.0427 ~~ 4.918
