Cut two cubes of potato of size 2 cm x 2 cm x 2 cm
Cut one of these cubes into 8 cubes of potato of size 1 cm × 1 cm x 1 cm
(sample A).
Do not cut the other cube (sample B).
Measure the mass of each sample A and the mass of sample B
Place all the cubes into a beaker of distilled water.
Leave for 30 minutes.
Remove the cubes from the beaker and dry the surfaces with a paper towel.
Measure the mass of each sample of cubes.
Why were 8 cubes of size 1 cm x 1 cm x 1 cm but only one cube of
size 2 cm x 2 chix 2 cm cube used?
