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

Step-by-step explanation:

In the given question we have to assume that the height of the square piece is 1 cm

Then Let the number of square piece be n.

Now, volume of iron piece = number of square piece × Volume of square piece

⇒ 1200 cm × 400 cm × 40 cm = n (4 cm × 4 cm × 1 cm)

Hence 1200000 square piece were made.
