Answer:
216 cubes.
Step-by-step explanation:
The easiest way to take on this problem is to divide the side of the bigger cube by the smaller one.

Then, as in with volume, we cube this value to find the number of cubes necessary to fill such a space.

Length of room = area / width
Length of room = 56/7 = 8 feet.

Answer:
A: 3/32+1/32 inch
Step-by-step explanation:
So we have the measurements 2/32 and 4/32. We are told the heights range between these two measurements.
What's between 2/32 and 4/32? 3/32.
Since the problem says "between", that must mean 2/32 and 4/32 are the limits of the height.
Now, if we add or subtract 1/32 from 3/32, we get the previous measurements listed.
Hope that helps!
