I also dont know how to calulate the volume of all 5o pennies. For the volume of just 50 pennies in the glass it raised the water to 4 spoonful marks.
Archimedes' Principle (hands-on 3) Determine the mass, volume and density of objects using Archimedes' principle. Materials needed: Clear drinking glass Measuring spoon Resealable pill bottle (small enough to be immersed in your glass Masking tape Roll of pennies Graduate the glass. Place a strip of tape vertically on the outside of the glass. Partially fill the glass with water and mark the height of the water on the tape. Add a spoonful of water and again mark the height. Repeat this about twenty times ( this is boring but cutting edge science can be that way) Restore water height to original level. Place some pennies in the pill bottle and place it in the glass. If it floats add more pennies. If it sinks remove some pennies. In this way determine the minimum number of pennies needed to totally immerse the bottle. Note the change in volume. Calculate the mass of the water displaced. This is approximately the mass of the bottle with pennies. Just for fun, put all 50 pennies in the glass and calculate their volume. Look up the density and current market value of copper. Assuming that a penny is pure copper, what is the material cost of a penny?Explanation / Answer
the mass of water displaced can be calculated by determining the change in the volume of water in the glass and multiplying this change in volume with density of water. the change in volume can be determined by subtracting volume of water without pinbottle from the volume after pin bottle is immersed .
to calculate the volume of 50 pennies , you can measure their total mass and divide that mass by the density of copper of which they are made up of
