Answer:
If three metallic solid cubes whose edges are 3cm, 4cm and 5cm are melted and formed into a single cube, then the edge of the cube so formed is = 6 cm
Step-by-step explanation:
Volume of new cube = Volume of 3 old cubes
Let the new side be X.
∴ X³ = 3³ + 4³ + 5³
∴ X³ = 216
So the Volume of Cube = 216 cm³
∴ X = 6 cm - Length of each side
