Answer:
$100\ cm^3$

Explanation:

Given

The ratio of mixture of sand and cement is 5:3

If the total volume of mixture is
$160\ cm^3$

Suppose there is 5x and 3x cubic centimeter of sand and cement respectively i.e.

$\Rightarrow 5x+3x=160\\\Rightarrow 8x=160\\\Rightarrow x=20\ cm^3$

Sand
$5x=5* 20=100\ cm^3$

So, there is
$100\ cm^3$ of sand in the mixture
