A tank in the shape of a rectangular prism measures 5 dm by 2 dm by 23 dm. The tank is completely filled with 8314.5 L of liquid.

What is the density of the liquid?

Density = Mass of Liquid / Volume of tank

The problem here is that the liquid isn't identified.....so.....determining its mass is impossible

However...assuming that we have water.....its mass is almost exactly 1kg per L

So 8314.5 L ≈ 8314.5 kg

So.....the density is

8314.5 kg / [ 5 * 2 * 23 ] dm^3 ≈ 8314.5 kg / 230 dm^3 ≈ 36.15 kg / dm^3
