Answer:

<em>Answer: C.Fraction 11 and 1 over 4 cubic inches</em>

Step-by-step explanation:

The volume of a rectangular prism of length L, width W, and height H is given by:

V=LWH

The prism is packed with cubes of a side length of a=1/2 inch. The volume of each cube is:

$V_c=a^3=\left(\frac{1}{2}\right)^3=\frac{1}{8}\ in^3$

The prism is packed with L=5, W=3, and H=6, thus the volume (in cubes) is:

V=5*3*6=90\ cubes

Since each cube has a volume of $\frac{1}{8} in^3$ :

$V=90\cdot\frac{1}{8}=\frac{45}{4}$

Expressing as a mixed fraction:

$V=\frac{45}{4}=\frac{44+1}{4}=11\frac{1}{4}$
