Answer:
The cube's volume can be represented as 8y^3 when expressed in terms of y.
Explanation:
The side length of a cube is given as 2y. To express the volume of the cube in y, we can use the formula for the volume of a cube which is given as V = s^3, where s is the length of one side of the cube.
Substituting 2y as the length of the side of the cube, we get:
V = (2y)^3
Simplifying, we get:
V = 8y^3
Therefore, the volume of the cube expressed in terms of y is 8y^3.
