Alex should use Easyvans because if he gets a car they will charge more money per season so he would get charged 172 per season so if he got the other one you dont have to pay you just pay once.
<span>I think the height is 2/3 that of a side of the base. If that is correct, then the height is h = 2/3s.
The formula for the volume of a pyramid is \[V=\frac{ 1 }{ 3 }s ^{2}h\]
Normally it would be B for base area, but since this is a square and the height is in terms of s, that would be the formula.
If we find the area based on the fact that h = 2/3s, then it appears that the formula would be
V=1/3s^2 x 2/3s
If you multiply that all out, it would be V= 2 / 9s ^3
