ok
so
a. realisically, a cube with side length1 can't fit since 1>1/2 and the cube would stick out
but, if they wanted us to melt the cube or something
find volume of prism and divide that by th evolume of the cube
volume prism=1/2 times 2 times 7/2=7/2 cubic inches
volume cube=side^3=1^3=1
so
7/2/1=7/2
7/2 or 3.5 cubes can fit
b.
1/2 is the side lenght
so cuube volume1/2^3=1/8
(7/2)/(1/8)=(7/2)(8/1)=56/2=28
28 cubes can fit
