Answer:
Let the amount of iron piece be x
Amount of Copper piece=2x
Density of iron=7.8g/cc
Density of copper=8.9g/cc
Weight of iron=7.8x
Weight of copper=17.8x
Total weight=1280g
7.8x+17.8x=1280
25.6x=1280
x=50
Weight of iron=7.8×50=390g
Weight of copper=890g
Volume of iron=390/7.8=50ml
Volume of copper=890/8.9=100ml
hope it will be helpfull.....
