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?

Result

m =  16.666 kg

Solution:

$a=44.5/100=\dfrac{ 89 }{ 200 }=0.445 \ \\ b=30/100=\dfrac{ 3 }{ 10 }=0.3 \ \\ c=16/100=\dfrac{ 4 }{ 25 }=0.16 \ \\ V_{1}=a \cdot \ b \cdot \ c=0.445 \cdot \ 0.3 \cdot \ 0.16 \doteq 0.0214 \ \\ m_{1}=V_{1} \cdot \ 710=0.0214 \cdot \ 710=15.1656 \ \\ m=m_{1}+1.5=15.1656+1.5=16.6656=16.666 \ \text{kg}$
