How do you find the volume of a container?
This is not homework and I used to know this stuff but I have been out of school for so long the only gray matter I appearantly have left is in the form of hair. I am mucking around with some passive solar expirements for my own amusements. I want to make containers to hold 1 liter, 2 liters, or 4 liters of fluid with a depth of 1" to 2" max. My first expirment on a 40 degree day heated the water so that it was warm to the touch, but the container was not well insulated and the water was 4" - 5" deep. My next expirment will be with a liter of water 1" or 2" deep in a well insulated container. And this time I will make sure the batteries are not dead in the theormeter. Thanks for your help.
Furbag, if the height is 1" than multiplying your area by 1 will give the same answer as the area of the base.
For instance: I filled a cake pan with the dim of 7" x 11" x 2" which barely held two liters of water. The W x L x H =154"
If I take 11" x 14" x 1" this also gives me 154" But what troubled me was multipling the 1" into the area of the base did not increase the number. I can easily convert the numbers over to meteric and then I won't have to deal with the number 1. I just wanted to verfiy that I was doing the math right. Multipllying the base by 1 bothered me.

If the container is a regular cross-section like a rectangle or a circle, you will remember that the volume is given by cross-sectional area times height of fluid. Measure all dimensions in centimeters (not inches) and your answer will be in cubic centimeters.
1 cubic centimeter = i milliliter, of which there are one thousand in a liter.
If the cross section of your container is irregular, fill it to the desired height using a measuring cup and that will give you the volume

The easiest way to measure the volume of a container is to fill it with water and then weigh the water. If the metric system is used, then the weight in kilograms is the volume in liters. 1 cubic centemeter of water weighs exactly 1 gram in this system. A kilogram is approximately 2.5 pounds.
Calculating the volume of a regular container mathematically involves knowing the volume formula. If the container is a regular box shape, the volume is simply the width times height times depth. Inches can be used in this measurement and there are 231 cubic inches in 1 gallon of water. If a cylinder is being used, the formula is the radius squared times PI times the height. Again, use the cubic inches per gallon calculation to determine volume. Mathematics reference texts have formulas for the volume of a large number of solids.
hope this helps.

I know this is not your question, but to heat water with solar energy, you cannot have the top open, as heat losses from evaporation will take away all of the heat quickly. Depth is not an issue except that it takes longer to heat all the water.

so was that a question or wat?
if it was volume its the area of base times height.
