Does it say how many of the marbles in the bag are red? Normally you will want to divide the amount of red marbles to the amount total marbles and you will get a percent. It's also note worthy that it states the marble going back into the bag. It would change if it was left out still.
10x -4 (x - 2) = 80
10x + (8 + -4x) = 80
<span>8 + 10x + -4x = 80
</span>8 + 6x = 80
<span>8 + -8 + 6x = 80 + -8
</span><span>6x = 80 + -8
</span>6x = 72
<span>x = 12</span>

Answer: 1440
Explanation: when you split it into two shapes (I split it where the split is splitting the eight up) you find the volume of them both. Top shape= 4x4x10=80 bottom shape= 8x8x10=640.
640+80= 720
You will then need to multiply by two (or add 720+720) to get the answer 1440
