Fie prisma ABCA1B1C1
ABC=baza <A=90 grade
ml=muchiile laterale
mb1,mb2,mb3=muchiile bazei
___________________________
Aria unei fete=ml*mb1=13=>ml=1 si mb1=13
Aria fetei 2 =ml*mb2=30=>ml=1 si mb2=30
Deosebim 2 situatii
1)mb1 si mb2 catete=>
AB=13, AC=30
Conform Pitagora BC=radical 1069 care nu este nr natural
2)mb1=AB=13 si mb2=ipotenuza=BC=30
Conf Pitagora BC=radical731 care nu apartine lui N
