Question

A block of Iron has dimension 2m x 0.5m x 0.25m. The density of iron is 7.8g/cm3 . Find the mass of the iron block​

Answer 1

Answer:

Volume of Block=2×0.5×0.25

=0.25m^3

Mass of block=volume÷density

$\frac{7.8}{0.25 \times 100 \times 100 \times 100} \\ = \frac{7.8}{250000} \\ = 3.12 \times {10}^{ - 5}$
