How do you solve this problem

Answer:
V=[tex]8y^{15} ft^3[/tex]
Step-by-step explanation:
The volume of a cube is l*w*h, and since l,w,h are all the same multiply [tex]2y^5[/tex] by itself thrice and use exponent rules, which looks like this:
[tex](2y^5)^3\\(2)^3(y^5)^3\\8y^{15}[/tex]
If this helped, a brainliest would be greatly appreciated!
