Question 979247


The volume of the tank is   0.8 m x 0.8 m x 2.4 m = 1.536 {{{m^3}}} (cubic meters).

Since the water occupies initially only half of this volume,  the volume of water is   {{{1.536/2}}} = 0.768 {{{m^3}}},  or  768  liters 

(<B><U>reminder</U></B>: &nbsp;&nbsp;1 liter = 1 cubic decimeter = 0.001 {{{m^3}}}). 


To answer the problem's question, &nbsp;you need to divide this value by &nbsp;12: &nbsp;&nbsp;{{{768/12}}} = 64.
