To calculate the mass of the object, we need to use the formula: mass = volume x density. The volume of the object can be found by subtracting the volume of the lower plane from the volume of the upper plane. 
Volume of upper plane = (11eaa88b_92fc_24e4_a696_514243df36ac_TB5869_11 – 11eaa88b_92fb_fdd3_a696_87da4a194154_TB5869_11) = 11eaa88b_92fc_24e4_a696_4bcea4ba4f58_TB5869_11 
Volume of lower plane = (11eaa88b_92fb_fdd3_a696_87da4a194154_TB5869_11 – 0) = 11eaa88b_92fb_fdd3_a696_87da4a194154_TB5869_11 
Volume of object = 11eaa88b_92fc_24e4_a696_4bcea4ba4f58_TB5869_11 – 11eaa88b_92fb_fdd3_a696_87da4a194154_TB5869_11 = 11eaa88b_92fc_24e4_a696_c303c7e550d8_TB5869_11 
Therefore, mass = 11eaa88b_92fc_24e4_a696_c303c7e550d8_TB5869_11 x 11eaa88b_92fb_d6c2_a696_b7c842ad9e36_TB5869_11 = 11eaa88b_92fc_7307_a696_c3a95f64925d_TB5869_11. Thus, the best choice is C.
