Question

A piece of wood of mass 6 metric tonnes has a volume of 7.5×10 to the power 6 cm³.Find the density of wood in S. I. unit​

Answer 1

• Mass=6metric Ton=6×10^3kg
• Volume=7.5×10^6cm^3=7.5×10^8m^3

We know

$\boxed{\sf Density=\dfrac{Mass}{Volume}}$

$\\ \sf\longmapsto Density=\dfrac{6\times 10^{3}}{7.5\times 10^{6}}$

$\\ \sf\longmapsto Density=0.8\times 10^{-5}kg/m^3$

$\\ \sf\longmapsto Density=8000kg/m^3$
