To clarify my earlier comment, if you assume that the structure is a third of a cube, then the next third needs a base layer of 10×10. Putting this by the current structure will make a structure that is 11 melons high… so not a cube but now a cuboid.

]]>Interesting. a 10 by 10 cube would be a 1000 watermelons. But 1/3 of a 1000 is 333 1/3, not 385. I’m sure I’m missing something fundamentally wrong here? Verrry interesting. Makes me think.

]]>Great problem! Will use in my classroom tomorrow. Just added it to my “Real World Math” directory here: http://tapintoteenminds.com/3act-math/

Check ‘er out and keep up the great work!
