The eureka beaker is a beaker to find out the density of irregular shaped objects. Archimedes invented it when he stepped into his bath and saw that the water level rose. He shouted "Eureka!" which means "i have found it!".
Volume of a sphere = 4/3*pi*radius3 and legend has it that Archimedes was having a bath when he discovered the formula
Archimedes
it can be found by first taking the volume of the water itself and then the volume of the object in the water. you pour water into the 12-sided object, then measure the amount of water using the graduated cylinder. Then you do this: length x width x height = volume
irregular
In 212 B C Archimedes found buoyancy.
4/3 *PI* r3 The formula was first derived by Archimedes, who showed that the volume of a sphere is 2/3 that of a circumscribed cylinder.
Its density which is found by dividing the mass by the volume.
he discovered his invention when he was in the bath. and also he found out that objects float when there density is lower than the water e.g. o.24.
A cubic foot is a unit of volume. Generally, the number of cubic feet in any given 3 dimensional object can be found by multiplying the three dimensions together. Those dimensions being in linear feet. The volume of irregular shaped objects can be calculated by their displacement.
