1 The volume of the cube is 2 * 2 * 2 or 2 ^ 3 in ^ 3 while the
volume of the large box is 10 * 10 * 10 or 10 ^ 3 in ^ 3.
2 The answer is 125. Just divide the large box to the volume
of the cube 1000 / 8 = 125.
3 The box will hold the same number of balls as small boxes.
With the balls, there is empty space.
4 The answer is still 125. Just find the volume of the box
and of the cube. Divide the box volume by the cube volume.
10x+20y=540
x+y=34
y=34-x
Plug in (34-x) for y:
10x+20(34-x)=540
10x+680-20x=540
-10x=-140
10x=140
x=14
There were 14 ten cent coins and 20 20 cent coins
