Dimension of an iron block is 4.6inxx3.0...

Dimension of an iron block is `4.6`in`xx`3.0 in`xx`1.9in
and density of iron is 7.87/`cm^(3)`. Find out the mass of the iron block. [Given 1 in=2.54 cm]

Text Solution

Verified by Experts

Mass of the iron block
`=(4.6"in"xx(2.54cm)/(1"in"))xx(3.0"in"xx(2.54cm)/(1"in"))xx(1.9"in"(2.54cm)/(1"in"))xx(7.87)/(1cm^(3)))`
`=3.381xx10^(3)g=3.4xx10^(3)g` [After roundingg off].
