Canister

Gasoline is stored in a cuboid canister having dimensions 44.5 cm, 30 cm, 16 cm. What is the total weight of a full canister when one cubic meter of gasoline weighs 710 kg and the weight of empty canister is 1.5 kg?

Correct result:

m =  16.6656 kg

Solution:

$$\begin{gathered} a=44.5\mathrm{/}100={\displaystyle \frac{89}{200}}=0.445 \\ b=30\mathrm{/}100={\displaystyle \frac{3}{10}}=0.3 \\ c=16\mathrm{/}100={\displaystyle \frac{4}{25}}=0.16 \\ {V}_1=a\cdot b\cdot c=0.445\cdot 0.3\cdot 0.16\doteq 0.0214 \\ {m}_1=V_1\cdot 710=0.0214\cdot 710=15.1656 \\ m=m_1+1.5=15.1656+1.5=16.6656\text{ kg} \end{gathered}$$
