**98) Find the value of the volume of void if the porosity of soil is 0.7 & the volume of soil is 100m3?**

a) 50 m3

b) 60 m3

c) 70 m3

d) 80 m3

**Answer: c) 70 m3**

Explanation:Porosity is the ratio of volume of void to the total volume.

∴ n = (Vv / V ) x 100

∴ 0.7 = (Vv / 100 ) x 100

∴ Vv = 70 m3Hence, the volume of void is 70m3.
