8 inches

Explanation:

I am assuming since the units are given in cubic inches that 528 is the volume of the prism and not the area.

In this case

#" Volume " = lbh #

where l = length , b= w = width and h = height

hence lwh = 528

so #12xx5.5xxw = 528 → 66w = 528#

divide both sides by 66

#rArr " width " = cancel((66)w)/cancel(66) = 528/66 = 8#
