How do you calculate the weight of glass?
I am trying to calculate the weight of a fish tank. I know the weight of the water but I’m not sure of the weight of the glass.

Here’s a good way to do this:
Glass is mostly silicon dioxide, otherwiswe known as quartz. According to wikipedia, quartz has a density of 2.65g/cm3.
Now take the dimensions of the tank (if you only have an inch ruler, multiply each by 2.54. That gives you the answer in cm. multiply the length times the height, times 2, that’s two of the walls. Now the width times the height times 2, that’s the other 2 walls. Now the length times the width, that’s the floor. Add all 5 up. Now multiply that number by the thickness of the glass panels. That’s your volume of glass in cm3
Now assuming that the density of the glass and the density of quartz are the same (they are, roughly), all you need to do is multiply the volume of glass times the weight of glass per unit of volume (that’s called density) and you get the weight of the glass in grams.
If you need to give your answer in pounds, divide your answer by 454, since there are 454 grams per pound.

Two ways:
1) empty the fish tank and weigh it dry. or
2) weigh the fish tank plus water and subtract the weight of the water.

Alright. There are some basic concepts that you need to know.
1 cubic centimeter equals 1 gram. Simple right?
Now all you need to know is the length, width and height of your tank in centimeters. Multiply them together and the number you get is the weight of your tank (containing the water).
hope this helped! good luck.
