<p>If the volume of a cube is 8, what is the shortest distance from the center of the cube to the base of the cube?</p>
<p>The answer is 1, but I don't understand how to get this. It's probably something very easy and I'm missing it, lol. </p>
<p>Thanks in advance</p>
<p>You know that the volume of a cube is (side)^3 ... (if not, look at the formulas on page 733)</p>
<p>Now that you know one side, imagine a line going straight down from the center to the base below: it will be half a side.</p>
<p>A cube with volume 8 has sides of 2. That means that the center of the cube is at 1 unit high. Going straight down is the shortest distance, and therefore the answer must be 1.</p>
<p>Ahhhh, the center of the cube! I thought the question was asking what the distance from the center of the top to the bottom would be.</p>
<p>Thanks guys :)</p>
<p>That's why you read the question carefully, before you ask us.</p>
<p>dchow, I did read the question carefully, quite a few times actually. It's like staring at your essay and not seeing any grammatical errors until someone else proofreads it and points it out to you.</p>
<p>It's a free country.</p>
<p>Oh, come on, it's obvious that you didn't read the question carefully. Obvious, because if you had read it carefully, you would have found the mistake.</p>
