a)  Volume  =  (40 * 20 *  24) cm^3       =  19200 cm^3

 

b)  1L   =  1000cm^3

So  2L  = 2000 cm^3

 

So.....we can find how much the water wil rise  by  solving  this

 

(20 * 40  * h)  =   2000

 

800 *  h  =  2000     divide both sides by 800

 

h  =  2000/800  =  2.5 cm  =    height  that the water will rise

 

 

cool cool cool
