Question

Two solid cubes of side length 1m and 2m are melted and a single cube is formed. find the side length of the new cube​

Answer 1

Step-by-step explanation:

Volume of a cube = (side) ^3

Volume of cube having side of 1m = 1m^3

Volume of cube having the side of 2m = 8m^3

The resultant volume after adding

= 1 + 8

= 9m^3 ............i)

Now,

Let the side of new formed cube is x metre.

Its volume = x^3

By eqution i)

x^3 = 9m^3

$x = \sqrt[3]{9} m$
