Litres cubed doesn't exist because litres is alread a 3 dimensional term. However I assume you meant metres. So there are 670 litres in 0.67m3
8 liters
I would use 1 beef cube in 1/2 litre
1 000 000 cubes would be held. 1 000 litres of water.
well in 1 litre there is 1dm3 and in 1dm3 there are 1000cm3 so 1litre = 1000cm3 1cm3 = 0.001 litres hope that helped :)
488 cubes
3 cubes x 3 rows = 9 cubes
24 cubes would be it.
Coal cubes: 0. Sugar cubes: 0 Painted cubes: maybe some of them.
13 cubes 4,9,16,25,36,46,64,81,100,121,144,169,196
20 cubes
Assuming that the cubes are 1x1x1, there will be one thousand cubes in the larger cube.
A standard box of Rogers sugar cubes typically contains 60 cubes.
