What mass of water is contained in a tank whose dimensions are 100*cmxx50*cmxx30*cm?

Jan 21, 2017

We need (i) the volume of the tank.............

Explanation:

$\text{Tank volume}$ $=$ $100 \cdot c m \times 50 \cdot c m \times 30 \cdot c m$

$=$ $150000 \cdot c {m}^{3}$

But ${\rho}_{\text{water}} = 1 \cdot g \cdot c {m}^{-} 3$

And (ii) the relationship between mass, density, and volume.

Thus $\text{mass"="volume"xx"density}$

$= 150000 \cdot c {m}^{3} \times 1 \cdot g \cdot c {m}^{-} 3 \times {10}^{-} 3 \cdot k g \cdot {g}^{-} 1$

So that gives me over $100 \cdot k g$.
