Contest ends in

Not gonna lie. I've confused. I don't see how the first sqube is 72.

The first two primes are 2 and 3.

(2^2)x(3^3)=108

The second sqube.

Why am I being dumb?

I have tried to make my Java solution to this challenge fast enough. Has anyone managed to write a Java solution that is fast enough?

Alternatively can someone let me know which language they did use to solve the puzzle and score 100%.

can some post the solution in c++ ?
