One cuboid tank is 15 cm high, 12 cm long and 10 cm wide, and the other cuboid tank is 15 cm high, 8 cm long and 5 cm wide. Pour 2 liters of water into two tanks
In cuboid flume, make their water surface height equal, how many centimeters is the height of water in two flumes?
Add up the bottom area and divide it by 2000 ml, which is high
2000 ÷ (120 + 40) = 12.5cm
The quality factors 100, 98, 99, 188, 90 and 111 are decomposed by short division
100 = 4 X 25 = 2 X 2 X 5 X 5
98 = 2 X 49 = 2 X 7 X 7
99 = 9 X 11 = 3 X 3 X 11
188 = 4 X 47 = 2 X 2 X 47
90 = 9 X 10 = 2 X 3 X 3 X 5
