A tank in the shape of a rectangular prism measures 7 decimeters by 4 decimeters by 10 decimeters. The tank is completely filled with 10,690.4 liters of liquid.
What is the density of the liquid?
If I am guessing correct, the density is the amount of liters divided by the volume.
So the volume is $7\cdot{4}\cdot{10} = 280$
The density $10690.4\div{280}=\boxed{38.18}$
