Weight per square meter of 8-12 cm glass Easy to understand, clear can make people understand! In a word, it should be fast


The specific gravity of glass is 2.5 kg / cubic decimeter, which can be calculated according to its thickness. The calculation method is as follows: 25 δ
Description: δ - the thickness of glass, in mm
The unit of calculation is kilogram

10 mm thick glass weight per square meter


It's about 70 Jin



How much does glass weigh per square meter
How much does 1.2 weigh per square meter? 0.8


As long as it is flat glass, it can be calculated according to the following formula:
Weight (kg) = thickness × area × 2.5



Length 1.2 meters, width 80 cm, thickness 10 mm, how much is glass 3 fast?


The density of glass is 2.5 grams per cubic centimeter,
120 * 80 * 1 * 3 * 2.5 = 72000g = 72kg



How much does a cube of glass weigh
How much does a cubic meter of glass weigh


Glass is amorphous and has no uniform density due to different compositions
Usually we say the density of the crystal is actually a prerequisite, including how many degrees, how many atmospheres and so on
So if the owner wants to know, he can only measure the volume and weight of a small amount of glass by himself, and then calculate the average value according to the results of five times
At the same time, this result can only be used on one kind of glass, which will be different after changing



The weight of glass: how many pieces of glass is 1 square meter? 2mm, 3mm, 4mm, 5mm and 6mm, 8mm and 10mm 12mm


The density of ordinary glass is 2.5 * 1000kg / m3, the volume of 2mm, 3mm, 4mm, 5mm, and 6mm, 8mm and 10mm 12mm is 0.002 m3, 0.003 m3, 0.004 m3, 0.005 m3, 0.006 m3, 0.010 m3 respectively, and the mass is 5kg, 7.5kg, 10kg, 12.5kg, 15kg respectively



How much is a 1.5 times 1 glass


Five thick monolayers are about 40



The glass thickness of the flat mirror is 5mm, and the reflective film is coated on the back surface of the glass. If a light emitting point is 4mm away from the front surface of the glass, the image formed by that point is ()
A. 14 mm B. 13 mm C. 9 mm D. 4 mm


The thickness of the plane mirror is 5mm, and the distance between the light-emitting point and the front surface of the glass is 4mm, so the distance between the light-emitting point and the reflecting surface is 5mm + 4mm = 9mm. The distance between the image formed by changing the point and the reflecting surface is 9mm, so the distance between the image and the front surface is 9mm + 5mm = 14mm



Why is the thicker the glass, the worse the strength
For example, glass smaller than 12 mm and glass larger than 12 mm, why is the strength of the latter worse than the former?


There is a factor of early material and later processing. The less alkali the glass material contains, the better. The thicker the later tempering is, the less easy it is to toughen thoroughly. These are all factors that affect the strength, so we need to control from the source to get high-quality glass
