When the bottle is placed upright, the height of the drink is 16 cm; when the bottle is placed upside down, the height of the rest is 4 cm How many milliliters is the drink in the bottle? Please explain why
Height of bottle = 16 + 4 = 20 cm
Beverage height = 16 cm
So:
What are the drinks
=250÷20×16
=200 ml
The volume of a beverage bottle is 6 liters, and its body is cylindrical. Now some drinks are contained in the bottle. The height of the drink is 24 cm when it is placed upright, and the height of the rest part when it is placed upside down is 6 cm. How many liters of drinks are there in the bottle
1127881480,
6 × 24 / (24 + 6) = 4.8 (L)
There is a kind of beverage bottle with a volume of 30 cubic decimeters. The height of the beverage is 20 cm when it is placed upright and 5 cm when it is placed upside down. How many cubic decimeters are there in the bottle
20 + 5 = 25 cm ^ 30 cm ^ 3 = 30000 cm ^ 3 / 25 = 1200 cm ^ 1 200 × 20 = 24000 cm ^ 3
The volume of a drink bottle is 3 cubic decimeters. Now it contains some drinks. The height of the drink is 20 cm when it is placed upright, and the height of the rest is 5 cm when it is placed upside down. How many cubic centimeters of drinks are there in the bottle?
3 cubic decimeter = 3000 cubic centimeter
Set the bottom area of the beverage bottle as s square centimeter
From the problem, the equation can be listed
20S＝3000－5S
That is, 25s = 3000
The solution is s = 120
Beverage volume
＝20S
＝20×120
= 2400 CC
Therefore, there are 2400 cubic centimeters of drinks in the bottle
