--------------
The sides of a cube are equal.
It's not possible to make a rectangular solid with 6 sides that are 5 by 7.
No can do. In the first place, if you really have a cube, then all 6 of the faces must be squares and squares have equal measure sides -- not 5 feet by 7 feet. On the other hand, if you have a rectangular solid, it is possible that 4 of the 6 faces could be 5 by 7, but the remaining two faces in that case must be squares -- either 5 by 5 or 7 by 7.
Figure out the area of each of the 6 faces of your solid figure, then add up the 6 areas.
