62480÷ 16=3905 yuan
4,6 square decimeters =600 square centimeters
600× (26- 17) = 5400 cubic centimeters.
5500 ml =0.5 liter =0.5 cubic decimeter
40÷4= 10 decimeter
10×10×15 ÷ 0.5 = 3000 bottles
6,50 cm =5 decimeters 200 liters =200 cubic decimeters
200(5×5)= 8 decimeters =80 cm
7.4× 4× 4-8× 6× (4-2.8) =6.4 cubic decimeter =6.4 liters
8. (1) 50× 40× 30 =60,000 cubic centimeters = 60 liters
(2)10× 60 = 600km
The area of 9 and 8 blocks in a row is the largest: 8×/kloc-0 /× 4+/kloc-0 /×/kloc-0 /× 2 = 34 square decimeters.
The surface area of a cube is the smallest: 2×2×6=24 square decimeters.
10,21÷ 3 = 7 cm.
Cut a square with a side length of 7 cm from the four corners, so that a cube with a side length of 7 cm can be made.
Cut a square with a side length of 4 cm from four corners, so that a cuboid with a length and width of 2 1-4× 2 = 13 cm and a height of 4 cm can be made. 13× 13×4=676 cubic centimeters.
1 1, 900mm×685mm×745mm, that is, 900mm long, 685mm wide and 745mm high.
900× 685× 745 = 459,292,500 cubic millimeters =459.2925 cubic decimeters.
