<p>Haha, we still understand, prelewd.</p>
<p>im in calc ab & i've never learned anything about these parallel planes...should i have (b/c if i shouldn't have it WILL NOT be on the SAT)</p>
<p>and why if there are 24 rt angles in a cube, why does the answer change b/c it asks abt edges?</p>
<p>Well at least I'm leaning toward 24 again & feeling better abt myself, but if I'm wrong I'm wrong. =)</p>
<p>Well, you use the edges as your angles, right?</p>
<p>In a xy coordinate system, you are dealing with one plane. In an xyz coordinate system, you are dealing with two planes. Planes are a geometry topic. 24 right angles are formed by the edges in a cube, but the faces can intersect at right angles, which be different from intersection by the edges, since there are less faces than edges.</p>
<p>Find me one website that says a cube has 24 right angles and I will admit defeat</p>
<p>Er... I meant "line segments" for your right angles.</p>
<p>Are you ready to admit defeat?</p>

<p>Scroll down at 1/3 of the way down and look for the number "24".</p>
<p>EDIT: Actually, more like 1/4 of the way down.</p>
<p>yeah put in "24 right angles" w/ cube separate you get a bunch</p>
<p>Thats good. I put down 24. I was just BSing you guys. Want to pet my chode?</p>
<p>A cube is a solid symmetrical figure in the physical dimension. It has six faces, all of which are squares. A square has four right angles, a cube has 24 right angles, which means it has six-fold the hard angles or aspects of a square. Therefore, the quality of a cube is indicative of extremely difficult times.</p>
<p>Nice job powerabe.</p>
<p>BS or not, I was more than happy to help.</p>
<p>i like how someone went through the trouble to look up web material to support the answer.. what nerds we are</p>
<p>I was just followin this guys lead</p>
<p>Zack, your a moron. There are 12 edges on a cube and therefore there must be 12 distinct right angles.</p>
<p>You're analyzing that question too much. There are no right angles along the edges, it's where the intersect. And at the intersection of edges there are 3 right angles -- and there are 8 intersections. Or, you can just think of each individual face of the cube, which each have 4 right angles -- in this case, there are obviously 6 sides, and 6 x 4 again is 24.</p>
<p>Oh Zack, I liked you better on Saved By the Bell</p>
<p>No hard feelings, guys. I understand how you thought it was 12, Cookie. Well, at any rate, I hope you guys scored extremely well on the SAT :)</p>
<p>What about on Power Rangers?</p>
<p>I'm also a "Lego Maniac."</p>
<p>Oh man if the question said "BY the edges", then I've been looking at the question all wrong. I thought it said "AT the edges". Thanks to everyone for clearing that up. If it said "BY" then it's 24 for sure. Whew...</p>
<p>it's 24. duh.</p>
<p>I just saw that one corner will form 3 right angles, so 8 x 3 (8 corners total)=24</p>
