Question

Three metal cubes whose edges measure 3cm , 4cm, 5cm respectively are melted to form a single cube find its edge.

Answer 1

Answer :

The edge of a single cube after melting these three cubes is 6 cm.

Step-by-step explanation :

Given, three metal cubes whose edges measure 3 cm , 4 cm, 5 cm respectively are melted to form a single cube.

Sum of volume of three cubes = Volume of a single cube

⇒ (3)³ + (4)³ + (5)³ = a³

⇒  27 + 64 + 125 = a³

⇒  216 = a³

⇒  ³√216 = a

⇒ a = 6 cm
