The length of a square steel is 31.4cm, and its bottom is a square with a side length of 10cm. If it is made into a cylindrical steel with a bottom radius of 5cm, the length should be calculated

The length of a square steel is 31.4cm, and its bottom is a square with a side length of 10cm. If it is made into a cylindrical steel with a bottom radius of 5cm, the length should be calculated

Glad to answer for you!
4 × 10 × 10 = 3140 (CM & # 179;) original volume
3140 △ (3.14 × 5 & # 178;) = 4 (CM) long

A square steel is 31.4cm long and its bottom is a square with side length of 10cm. If it is forged into a cylindrical steel with bottom radius of 5cm, how long is the steel?

4 × 10 × 10 = 3140 (CM & # 179;) original volume
3140 △ (3.14 × 5 & # 178;) = 4 (CM) long

Hello! Please ask a question: in a cylindrical bucket with a bottom radius of 10cm, there is a cylindrical steel with a radius of 5cm immersed in water,
When the steel is taken out of the barrel, the water in the barrel drops by 2cm. How long is the length of the steel?

Steel volume: 10x10x3.14x2 = 628 cm3
Steel length: 628 / (5x5x3.14) = 8 cm

How many jin is 2000 ml?

4 jin, 500 ml for 1 jin

How many jin is 800 ml

You need to know the density
If it's water, it's 800g, 1.6kg

6.8 ml = () CC 550 cubic decimeter = () l 2000 ml = () l = () cubic decimeter

6.8 ml = (6.8) CC 550 cubic decimeter = (550) l 2000 ml = (2) l = (2) cubic decimeter

Fill in the appropriate score in the horizontal line. 45 points =___ Hours; & nbsp; 120 g = 0___ Kg; 1 cubic decimeter, 80 cubic centimeter___ Cubic decimeter

45 minutes = 34 hours; 120 grams = 0.12 kg; 1 cubic decimeter 80 cubic centimeter = 1.08 cubic decimeter, so the answer is: 34, 0.12, 1.08

How much is 2000 cubic centimeter converted into liter

1 cubic centimeter = 1 ml, 1 cubic decimeter = 1 liter, 2000 cubic centimeter = 2 cubic decimeters = 2 liters

How many tons is 2000 kg

2 tons

How many kilos is 2000 Jin? How many kilos is a load?

1kg = 2kg, 2000kg = 1000kg = 1T
The word "Dan" is "Shi", and the ancient "Shi" is the unit of measurement. To be exact, 1 Shi = 59.2 kg
