Find the weight of solid rectangular iron piece of size `50 c m\ xx\ 40 c m\ xx\ 10 c m ,\ ` if `1c m^3` of iron weighs `8gm`.

Text Solution

Verified by Experts

Dimension of rectangular iron piece`=50cm×40cm×10cm`
Volume of solid rectangular`=50×40×10=20000cm^3`
Weight of `1 cm^3` iron`=8gm`.
`∴`Weight of `20000cm^3` iron`=8×20000=160000 gm=160 kg`
Hence, the weight of the solid rectangular iron piece is `160kg`.
