You could first soak the sponge in water, then use the standard method of measuring irregular objects: fill a graduated cylinder with 100 mL of water, then drop in the wet sponge and see how much the water level rises.
This volume can be measured in millilitres.
Liter is a measure of volume. Volume = mass/density.
The volume of a liquid.
mL
liters
a large beaker and sponge
You can go by volume instead of weight.
mililiters
A sponge volume is mostly air.
Weight. (Since fluid is squeezed out, the compressed sponge weighs less). However, if the question refers to compressing a dry sponge, then the only quantity that would change would be volume.
My penis
you measure liquid or volume.
A sponge volume is mostly air.
You would determine the volume of water it displaces and measure it.
no; they have the same volume but their mass is quite different; density is mass/volume and the sponge has much lower density
You would use a tape measure.
I would use to measure a volume of a glass liters. Signed Luini, liters are bigger than milliliters and liters are about the volume of a glass.
