Let n be a number of balls: n = 14
In one pan you have 8 balls: 8n
In the other pan you have the rest of balls (14 - 8 = 6) along with a <span>weight of 20 grams = 6n + 20
So the pans are balanced:
8n = 6n + 20
Now, just solve the equation:
8n - 6n = 20
2n = 20
n = 20/2
n = 10
So, you know that a ball weights 10 grams.</span>

Answer:
<em>The volume of prism is length*width*height` V=23*14.2*8=2612.8cm^3</em>
<em>Rounded to the nearest whole number` 2613cm^3.</em>
<em>The volume of cylinder is S*height, where S is the area of circle,</em>
<em>S=Pr^2 -> V=3.14*8*8*23=4624.42cm^3. Rounded to the nearest whole number` 4624cm^3.</em>
<em>The difference between their volume is 4624-2613=2011cm^3.</em>
