Fill in the appropriate numbers in the brackets. 500ml = _ _ _ _ _ _ _ dm3 = _ _ _ _ _ _ l960 cm3 = _ _ _ _ _ _ _ dm3 = _ _ _ _ _ _ _ l400 dm2 = _ _ _ _ _ _ _ cm2 = _ _ _ _ _ _ _ m 2 100ml = _ _ _ _ _ _。 9, the ratio between two adjacent area units is _ _ _ _ _. 10, rectangular land is 50 meters long, 80 meters wide and 20 meters high, with a land area of _ _ _ _ square meters. Second, the judgment question. (10×1=10)1.A cuboid has at most eight identical edges and six identical faces. () 2. A cube with a length of 6 cm has the same surface area and volume. ............................... () 3. The sum of the sides of a cube is 6dm, so its surface area is 2 16dm2. () 4. The volume of the object must be less than the volume. ………………………………………………………………………………………………………………………………………………………………………………………………. 6, 3x=xxx, x3 = x+x+x........................................................................................................................................................ () 8. Cubes are special cubes. .............................. () 9. Two cuboids with the same volume must have the same surface area. .................. () 10, two cubes with the same surface area must have the same volume. .................. () Third, multiple-choice questions. (10×1=10)1.A rectangular frame with a length of 10cm, a width of 4cm and a height of () can be welded with a wire with a length of 64cm. A, 1cmB, 2cmC, 3cmD, 4cm2, the side length of the cube is enlarged by 2 times, the surface area is enlarged by () times and the volume is enlarged by () times. Cubes A, 2B, 4C, 6D, 83 with side length of 1m can be cut into () cubes with side length of 1cm.
