The diagram is given as:

Given,

The Volume (V) of each cube is = 64 cm

^{3}This implies that a

^{3}Â = 64 cm^{3}âˆ´ a = 4 cm

Now, the side of the cube = a = 4 cm

Also, the length and breadth of the resulting cuboid will be 4 cm each. While its height will be 8 cm.

So, the surface area of the cuboid = 2(lb+bh+lh)

= 2(8Ã—4+4Ã—4+4Ã—8) cm

^{2}= 2(32+16+32) cm

^{2}= (2Ã—80) cm

^{2}Â = 160 cm^{2}
