Answer:

Porosity of sample = 25%

Explanation:

Given:

Total volume = 400 cubic centimeters  

Pore space volume = 100 cubic centimeters

Find:

Porosity of sample

Computation:

Porosity of sample = [Pore space volume / Total volume]100%

Porosity of sample = [100 / 400]100%

Porosity of sample = [1/4]100%

Porosity of sample = [0.25]100

Porosity of sample = 25%
