<p>People have been saying that they spent a long time on the 3600 problem.
How did you guys solve the 3600 problem on the SAT?</p>
<p>I just did</p>
<p>24 * 10 = (2<em>2</em>2<em>3)</em>(5<em>2) then since 3 and 5 are not paired, multiply 3</em>5=15</p>
<p>240*15 = 3600</p>
<p>Well, I knew that only multiples of ten that are square are divisible by 10, so I kept squaring multiples of 10 until one was divisible by 24.</p>
<p>I kept on punching in everything into my calculator…</p>
<p>24 * (multiples of 5s)</p>
<p>I finally reached 150 and got the answer lol. This was such a time consuming question for me.</p>
<p>Hahahahaha.
20^2. Nope.
30^2. Nope.
… finally
60^2. YES!</p>
<p>Yeah I got 120 but then realized that it had to be the square of an integer. But by then it was too late and I ran out of time…oh well. What is the right answer then?</p>
<p>lol @ mascara: my thought process EXACTLY</p>
