Question

An iron piece 12 m × 4 m × 40 cm was melted into square pieces of side 4 cm each. How many cubes were made? *

Answer 1

Answer:

3000000 Cubes will be formed.

Step-by-step explanation:

$l$ of iron piece= 12 metres

$b$ of iron piece = 4 metres

$h$ of iron piece = 40 centimetres = 0.4 metres

$a$ of the cube = 4 centimetres = 0.04 metres

No. of Cubes =$\frac{Volume of Iron Piece}{Volume of Cube}$

No. of Cubes =$\frac{lbh}{a^3}$

No. of Cubes =$\frac{12*4*0.4}{0.04^3}$

No. of Cubes =3000000
