Question

three metal cubes with edges 3cm,4cm,5cm melted together and formed into one cube find its volume

Answer 1

volume of cube=3^3+4^3+5^
Edge^3=27+64+125
Edge^3=216
Edge= 6cm

Answer 2

Answer:

Volume of Cube = 216 cm³

Length of each side  = 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
