<PRE><B>Question 867596</B>
{{{10000*liter*1000(ml/liter)*1(cm/ml)^3*(1/100)^3(m/cm)^3}}}
{{{10000*1000/(1000000)=(10^7)/(10^6)}}}
10 cubic meters for 10000 liters.
The tank is 10 cubic meter capacity.


LENGTH of tank?
L = length of tank.
{{{L*2.2*2.4=10}}}
{{{L=10/(2.2*2.4)}}}
{{{L=1.894}}} meters tank length.


How full the tank with 20 mm of water?
Length is 1.894, and width is 2.4, meters each.
The rain height is {{{20*10^(-3)}}} meters.
How full, ratio of rain volume to tank capacity.
The fraction full is {{{(20*10^(-3)*1.894*2.4)/10}}}
{{{2*10^(-2)*10^(-1)*1.894*2.4}}}
{{{2*1.894*2.4*10^(-3)}}}
{{{9.09*10^(-3)}}}
-
The tank is {{{highlight(0.00909)}}} full.</PRE>
