I need help plz this is for a test

A

Step-by-step explanation:

So they've told you that the volume can be found using the equation . They've also indirectly told you what s is: 2/5 yards.

All you need to do now to find the volume is substitute the value of s=2/5 yards into the equations they gave you: .

so:

V = .

   = ()^3

So to solve that:

2^3 = 8 (same as 2x2 x2 )

5^3 = 125 (same as 5 x 5 x 5)

So now you have the fraction 8/125, so the answer is A: 8/125 cubed yards.

hope that helped : )
