To start, we know to find the density of an object, you must use the formula density= mass/volume. Since we already have the mass, we need to find the volume to find density. This would be multiplying the length, the height, and the width of the object together to find it which is: 2*1*5 which is 10 cm. Now that we know the volume and mass, we plug the values in the formula so that it looks like this: Density=6.8/10
Now, we solve and you get your density is 0.68.
