1, their volumes are different, so are boxes with the same volume. Due to the different wall thickness, the volume is also different.
2.3× 2.5× 2 =15m2
3, ml l square meters
4、2500 0.6 3250 0.45
5.87.5× 50× 56 = 24,500 square centimeters = 245 liters
6.1500ml =1.5l18 ÷1.5 =12 bottles.
7.15cm =1.5dm5.5l = 5.5 square decimeter.
2×2× 1.5-5.5=0.5 square decimeter.
8、8.04 8040 2750 2.75 7.5 7500 785 0.785
9700 ml =0.7L 14÷0.7=20 minutes.
10, and the internal dimensions of the cavity are the length, width and height of the microwave oven. Don't forget to convert units when calculating.
400× 225× 300 = 27 million cubic millimeters
2700000000 cubic millimeter =27 cubic decimeter =27L
1 1, 80000÷(50×25× 1.2) ≈53
12. If it is a soft and deformable object, you can knead it into a cuboid or cube, and then measure the required data with a ruler to get the volume. If it is a non-deformable object, drainage can be used.
13, 18.6×2. 1=39.06 cubic meters.
14,1.33× (13× 2.7×1.5) = 70.0245 tons.
15,22×10×1.8 = 396 cubic meters.
16. When a big ball and a small ball are put in,12ml; Discharge of water; Put in a big ball and four small balls and release 24mL of water, and you can calculate the displacement of the three small balls, that is, the volume of the three small balls. Divide the volume of three small balls by three to get the volume of one small ball, and finally get the volume of the big ball.
24ml = 24c m3 12ml = 12 cm3。
Small: (24- 12)÷3=4 cubic centimeters.
Size: 12-4=8 cubic centimeters.
