Question

a metal rod of dimension 180 cm into 120 cm into 100 cm is melted and recast into a cube if the length of each is 60 cm how many cubes are formed​

Answer 1

Answer:Here the key is that amount of metal is same so.

Volume of rod = combined volume of all the cubes formed.

Let x cubes are formed.

=> Volume of rod = x × Volume of 1 cube

=> x = volume of rod / volume of cube

=> x = (180 × 120 ×100)÷(60 ×60 ×60) = 10

So, 10 cubes can be formed.

Answer 2

10

X x volume of 1 cube

X (180 x 120 x 100) divide (60 x 60 x 60) ans 10
