If three cubes of copper, each with an edge 6 cm, 8 cm and 10 cm respectively are melted to form a single cube, -Maths 9th

1 Answer

Answer :

20.8 cm Let the edge of the single cube be ‘a’ cm.  Then, total volume melted = Volume of cube formed  ⇒ (6)3 + (8)3 + (10)3 = a3  ⇒ a3 = 216 + 512 + 1000 = 1728 ⇒ a = 12 cm.  ∴ Diagonal of the new cube = 3–√a=(3–√×12)3a=(3×12) cm = 20.8 cm (approx.)
