I would suggest turning all fractions into improper then multiply.
76 and 2/3 = 230/3
44 and 1/4 = 177/4
1 and 3/8 = 11/8

reduced becomes
which is
4664 + 11/16 cubic inches

(76 2/3)(44 1/4)(1 3/8)
[(228+2)/3][(176+1)/4][(8+3)/8]
(230/3)(177/4)(11/8)
(8*230)(6*177)(3*11)/24
(1840)/24*(1062)/24*(33)/24
64,484,640/13,824=4664.6875 OR 4664 55/8 ANS.
