The answer can be found by subtract the volume of the small box from the volume of big box.
Volume of the small box:
12*8*4= 384 inches cube
Volume of the big box:
20*15*9= 2700 inches cube
The space left:
2700 - 384 = 2316 inches cube
X=3 because you subtract the three on both sides to get x alone. So you get: 7x=21 then you divide seven by 21 and get x=3
Answer:

=16/100
=0.16
