A tank in the shape of a rectangular prism measures 10 decimeters by 4 decimeters by 6 decimeters. The tank is completely filled with 8908.8 liters of liquid.
Density is the mass of a substance per volume it occupies. But, it seems the items given are only the volume in liters. Assuming that it is mass, we do this:Density = 8314.5 / (5x2x23) = 36.15 L/dm^3 Hope this helps!
