2 faces have area = 6 cm * 8 cm = 48 cm^2
2 faces have area = 6 cm * 10 cm = 60 cm^2
2 faces have area = 8 cm * 10 cm = 80 cm^2
So the only possibilities for any 2 faces are:
48+48, 48+60, 48+80, 60+60, 60+80, 80+80
2 faces have area = 6 cm * 10 cm = 60 cm^2
2 faces have area = 8 cm * 10 cm = 80 cm^2
So the only possibilities for any 2 faces are:
48+48, 48+60, 48+80, 60+60, 60+80, 80+80

your not going to learn if people tell you, this stuff is easy, especially if they give the answers (which you have not given).
