Question

A price of iron has specific gravity equal to 8 and its with is 400 gm if its immersed in oil with specific gravity 0.8.what will be the with of this piece ​

Answer 1

Explanation:

density=0.8 gram/cc

=mass/vol

=sg divided by 1 and we write units too in density.

=400/v

so

vol=400/8=50 cc

(take weight as mass for practical purpose)

For width we need to know whether the piece of iron is a cube or else we need length and thickness or height.

Till then Question and answer both are incomplete.
