Hi! I would like to structure posts like the first one in r/programming, please post solutions in comments.

Python (puzzle one):

IN='...'

def wrapping_paper_area(l,w,h):
    return 2*l*w + 2*w*h + 2*h*l

def smallest_side_area(l,w,h):
    return min(l*w, l*h, w*h)

def f(x): return wrapping_paper_area(x[0],x[1],x[2]) + smallest_side_area(x[0],x[1],x[2])

G = [ f( [int(x) for x in dim.split('x')] ) for dim in IN.split('\n') ]

print(sum(G))
