the image here is missing the diagram of the cuboid (the first sentence says "... as shown...", so this question must have a diagram)

am assuming that ...
x is the length of the square base of the cuboid &
y is the height.

by forming 2 equations & solving simultaneously, can get x = 4.4 m & y = 7.0 m. mathematically, this is the answer, but does not make physical sense because cannot form such a large structure with just thin wire along the edges.

please check the diagram & amend the equations if my assumptions of the dimensions are not correct. method should be like this, just form 2 simultaneous equations & solve.
