Answer:

iii) 6cm is the correct answer

Step-by-step explanation:

volume of cube of side 3,4,5 cm is 27,64,125 respectively

we know on melting these cubes their volume remains same

therefore net volume = 27+64+125=216

So, volume of new cube =216

by using formulae of cube

we get side of cube =6 cm
