Question

Оконное стекло имеет обьём 400см в квадрате кокова её масса

Answer 1

M = pV 

p - плотность ( для оконного стекла 2500 кг / м3)
V - объём ( 400 см3 = 0,0004 м3)

m = 2500 * 0,0004 = 1 кг 
 

Answer 2

Calculating the Mass of Window Glass

To calculate the mass of the window glass, we can use the formula:

mass = volume × density

Given that the volume of the window glass is 400 cm², we need to find the density of the glass to calculate its mass.

Finding the Density of Glass

Unfortunately, the search results provided do not contain specific information about the density of glass. Therefore, I am unable to provide the exact density of the glass based on the available information.

If you have the density of the specific type of glass, you can use the formula mentioned above to calculate the mass of the window glass. If you need further assistance with this calculation or have any other questions, feel free to ask!
