How to calculate the weight of water The fish tank is 0.78 meters long, 0.38 meters wide and 0.45 meters high. Who can help me figure out how much water I can hold

Volume of fish tank = 0.78 * 0.38 * 0.45 = 0.13338 M3
Density of water = 1kg / m3
Weight of water = volume of fish tank * density of water = 0.13338kg = 0.26676kg

What's the weight of water?
The fish tanks are: length: 0.8 m, width: 0.14 m, height: 0.35 M. how can we calculate the weight of water

First calculate the volume of the fish tank, multiply by the density of water, 1.000 g / ml = the mass of water
Mass of water x9.8n/kg = weight of water

The weight of water at 24 ℃ is relative to the volume
Who knows, it's better to send a comparison table

Water temperature (℃) density (g / cm3)
15 0.99913
16 0.99897
17 0.99880
18 0.99862
19 0.99843
20 0.99823
21 0.99802
22 0.99780
23 0.99756
24 0.99732
25 0.99707

Various formulas of cylinder
Surface area
volume

Cylinder formula
cylinder
v: Volume H: height s; bottom area R: bottom radius C: bottom perimeter
(1) Side area = perimeter of bottom surface × height
(2) Surface area = side area + bottom area × 2
(3) Volume = bottom area × height
(4) volume = side area △ 2 × radius

Finding the weight of a cylinder
The diameter is 280 cm, the height is 160 cm, and the composition is iron

V = π R & # 178; × H = 3.14 × (280 / 2) & # 178; × 160 = 9847040 cm3
The density of iron is 7.8
Weight of cylinder: 9847040 × 7.8 = 76806912g

Find the weight of the cylinder, diameter 6, height 10. The density is 1.16/mm3

3.14×（6÷2）²×10×1.16=327.816

A cylinder is 9mm in diameter and 21mm in height. I want to find the weight of a cylinder

I don't know how to keep your decimal point, but the method is as follows:
M = ρ V (mass = density * bulk density)
V = sh = π (D / 2) ^ 2 * H = 3.14 * 0.45 ^ 2 * 2.1 = 1.335285cm ^ 3 (volume = bottom area * height)
ρ = 7.9 g / cm ^ 3, right? So the unit above should be the same. Change millimeter to centimeter
m=7.9*1.335285≈10.55g

Know the diameter and material density and quality ~ help calculate the length of the cylinder!
The diameter of the cylinder is 150 mm and 190 mm. The density of the material is calculated by 7.85. The mass is 235.4 kg and 246.1 kg. Please help me calculate how long the material is needed for 150 mm and 190 mm under 235.4 and 246.1 masses! ~ ~ ~! Thank you for waiting online
Please give the calculation method and results.. Urgent need.. thank you

M=ρV=ρLπD^2/4
L=M/(ρπD^2/4)
The corresponding length is calculated with M = 235.4kg and diameter of 150mm:
L=M/(ρπD^2/4)=4M/(ρπD^2)
=4*235.4/(7.85*1000*3.1416*0.150^2)
=1.697 M
Please calculate the rest of the data by yourself

How much is a stainless steel 304 cylinder with a diameter of 58 and a diameter of 36 and a height of 21?
Such as the title

About 270Kg. 540 Jin. Your unit is centimeter

An iron tank. Cylinder. Volume 300m3. Wall thickness 5mm. Iron density 7850kg / m3. Find the weight of the tank
The top is sealed

There is no shortage of conditions
1. In order to save space and material, the diameter and height of oil tank are the same
2. The oil tank has not only the upper sealing plate, but also the lower bottom plate
It's none of my business if I can't figure it out
