78 identical cubes each with 2 cm edge are joined together to form a cuboid. If the perimeter of t..

78=2*3*13, so to form a perfect cuboid the number of cubes on each side will be: 2,3,13

Since each cube has an edge of 2 cm, the dimensions of cuboid in cm will be: 4,6,26

so the perimeter of each of the sides will be 2(a+b) :
20,20,64,64,60,60

the base has perimeter 64, so the edges on the base are 6 and 26.

Therefore, the edge that is horizontal will be 4 cm, and thus the height is 4 cm.
