If only they’d brought a physicist…
This would be a neat “real life” problem for a maths or physics class: a bunch of record breakers tried to erect a giant iceblock, but it melted faster than expected, and flooded the square with strawberry and kiwi fruit juice. (mmmm….) For 5 points, based on the power output of the sun, its distance from Earth and gueestimating 20% of the power reaches the iceblock (or just looking up the actual power incident on earth - it’s on the web) calculate the rate at which the iceblock would melt, probably assuming a latent heat equivalent to water. The dimensions probably aren’t really important for this calculation, although the block was 7.6m high so you could assume scaling if you liked.
And, I’m sure there are lots of extension questions which could be amusing as well
