The equation below shows the total volume (v), in cubic units, of 6 identical boxes with each side equal to s units:
v = 6s3
if s = 3.1 units, what is the value of v?
111.6 cubic units
178.746 cubic units
554.113 cubic units
669.6 cubic units

- so we know that one boxe has volume equal s^3
 6 boxes has total volume equal 6s^3

so in the case when s=3,1 units ,just calcule s^3 so 3,1^3 equal 29,791 and multiplie it by 6 what is equal 178,746 cubic units 

what mean that the second choice is right sure --- !
