How to calculate the area of a steel plate with width, thickness and weight?

Use weight / specific gravity / (width * thickness). I look at it as a long cube, know its width, height (thickness) and weight, find its specific gravity (which is in the hardware manual), and then we can calculate its volume. Divide the volume by its bottom area (width multiplied by height) to get the length, and then multiply the length by width to get the area

How much is the weight of a steel plate with a length of 3 meters, a width of 2 meters and a thickness of 1 cm? How much is the weight of a steel plate with a length of 2.2 meters, a width of 1.8 meters and a thickness of 1 cm

A piece of steel plate is 3 meters long, 2 meters wide, 1 cm thick, and the weight of steel plate is 1
=(3*2*0.01)*7800
=0.06*7800
=468kg
A piece of steel plate is 2.2m long, 1.8m wide, 1cm thick, and the weight of steel plate is 1
=(2.2*1.8*0.01)*7800
=0.0396*7800
=308.88kg

How much is the checkered steel plate 6 meters long, 1.06 meters wide and 0.4 mm thick? How much is the steel plate 6 meters long, 1.51 meters wide and 1 cm thick? How do you know their calculation method

Mass = Volume X density, the density of steel is 7.8x10 cubic kg / m3
6x1.06x0.0004x7.8x10 = 19.8432kg
6x1.51x0.01x7.8x10 = 70.668kg

Is the theoretical weight of Q235 steel plate different from that of Q345 steel plate

There is no difference, the density is 7.85g/cm3

What is the difference between Q345 steel plate and Q235 steel plate?

Q345 steel is low alloy high strength structural steel; Q235 steel is carbon structural steel
The strength of Q345 steel plate is much higher than that of Q235 steel plate

A steel plate 30 cm wide, 60 cm long and 2 cm thick. What's its weight

028 tons

How much is the weight of the steel plate in a piece of 3mm thick, 55cm long and 33cm wide

The volume of the steel plate is
0.3 * 55 * 33 = 544.5 cm3
The density of steel plate, which is not given in the question, is generally calculated as 7.9g/cm3 according to the density of iron
544.5*7.9=4301.55g

What is the weight of a steel plate 1 m wide, 2 m long and 2 cm thick
I asked people how they calculated the 31.4 kg, which elder brother knew about it, and told my younger brother,

Mass = volume * density = length * width * thickness * density = 200cm * 100cm * 2cm * 7.85g/cm ^ 3 = 31400g = 314kg

The steel plate is 2 meters long, 6 meters wide and 20 mm thick

2 * 6 * 0.02 = 0.24m3 0.24 * 7.8 = 1.872t

How much does the steel plate weigh? It's 2 meters long, 6 meters wide and 16 mm thick?

Volume: 2 * 6 * 16 / 1000 = 0.192 LM
Density: 7800kg / M
Weight: 0.192 * 7800 = 1497.6kg
