Answer:
6 cm
Step-by-step explanation:
Length of the three cubes = 3 cm, 4 cm, 5 cm
The three solids are melted
Sum of the volume of the three cubes
= 3^3 + 4^3 + 5^3 cm^3
= 27 + 64 + 125 cm^3
= 216 cm^3
.'. Volume of the new cube = 216 cm^3
Edge of the new cube
= Cube root of Volume
= Cube root of 216 cm^3
= 6 cm (Ans.)
