A rectangular prism has a width of x inches, a length of x2 y inches, and a height of y2 inches. which expression represents the volume in cubic inches of this prism?

we know that
[volume of the prism]=L*W*H
L=x²*y in
W=x in
H=y² in

[volume of the prism]=(x²*y)*(x)*(y²)-----> x³*y³ in³

the answer is
x³*y³ in³
