Answer:
160 cm^2
Step-by-step explanation:
When two cubes of side 4 cm are fixed together, we get a cuboid with double the length of that of the cube, the same height and same width.
Dimensions of cuboid:
l = 8 cm b = 4 cm h = 4 cm
Total surface area of a cuboid is 2(lb + bh + lh)
= 2*(8*4 + 4*4 + 8*4)
= 2*(32 + 16 + 32)
= 2*80
= 160 cm^2
