Question

An iron piece 12 mx 4m x40 cm was melted into square piece is side 4 cm each how many pieces where made?​

Answer 1

Answer:

Step-by-step explanation:

Dimensions of iron piece=12m ×4m×40cm

12m=1200cm

4m=400cm

Volume=400×1200×40=19200000cm³

The piece was then melted and made into small cubes of side 4cm

Volume of each cube=4³=64cm³

No. of cubes made=19200000/64

=30,000

Answer 2

Step-by-step explanation:

let the no. of sq. piece be x

volume of iron piece =x*volume of square

12*4*0.4=x*0.04*0.04*0.04

192=x*0.000064

x=192/0.000064

x=30,0000

so,300000 square where made
