If you put a carton of one cubic decimeter on the table, the area of the carton must be one square decimeter

If all sides of the cuboid are 1 decimeter long, its area on the desktop is 1 square decimeter. If the length, width and height are not equal, its area on the desktop is not 1 square decimeter

After the mass of 0.9 kg of water becomes ice, the volume increases by 0.1 cubic decimeter. What is the density of ice

The volume of 0.9 kg water is 0.9 cubic decimeter
The volume of ice is 0.9 + 0.1 = 1.0 cubic decimeter
Ice density = 0.9 / 1.0 = 0.9kg/dm ^ 3
