Given dimensions of rectangular prism : 10dm * 4dm* 6dm
The tank is completely filled with 8908.8 gm
Volume of the tank = length * width * height
=> [tex]v= 10*4*6 = 240 dm^3[/tex]
We know, 1 cubic decimeter = 1 litre
[tex]240 dm^3= 240 litre[/tex]
It is obvious that, 8908.8 litres would not fit in a 240 l tank, so assuming 8908.8 gm.
We know, [tex]density =\frac{mass}{volume}[/tex]
Density = [tex]\frac{8908.8}{240}= 37.12 gm/l[/tex] ... Answer
