conversations.from: human
conversations.value: 9 out of 10 cheerleaders are 64" tall.  The 10th cheerleader is 60" tall.  If they build a human pyramid, where 4 girls are on the bottom,  3 stand on top of the 4, 2 stand on top of the 3 and the shortest girl is at the top, how tall is the human pyramid in feet?
  Give me a solution to this problem

conversations.value: All but one cheerleader is 64" tall and these cheerleaders make up the bottom 3 layers of the pyramid. So, when standing on top of each other, they are 64*3 = 192" tall
  The shortest cheerleader is at the top of the pyramid and is 60" tall so the pyramid is 192+60 = 252" tall
  12" are in 1 foot and the pyramid is 252" tall so it's 252/12 = 21 feet tall
