Answer 2

105 cubes of edge length 4 cm can be formed by melting the cuboid

Step-by-step explanation:

Given: Volume of big cuboid = 6720 cm³

It is meted to form smaller cube of length 4 cm

Now edge of cube = 4 cm

As we know Volume of cube = a³ where a is the edge of cube

We have to find the number of cubes can be formed after melting the cuboid

Let n is the number of cubes

Therefore

$n=\dfrac{\text{ Volume of cuboid}}{\text{Volume of new cubes formed }} = \dfrac{6720}{4\times 4\times 4} = 105$

Hence, 105 cubes of edge length 4 cm can be formed by melting the cuboid
