Answer and Step-by-step explanation:

To find the volume of the new cube, we can use the relationship between the surface area and the volume of a cube.

1. Determine the length of each side of the original cube:

Let's assume that the length of each side of the original cube is "x".

2. Find the surface area of the original cube:

The surface area of a cube is given by 6 times the length of one side squared. Therefore, the surface area of the original cube is 6x^2.

3. Set up an equation based on the given surface area:

We are given that the surface area of the original cube is 96 square yards. So, we can write the equation as:

6x^2 = 96

4. Solve the equation for the length of each side:

Divide both sides of the equation by 6:

x^2 = 16

Take the square root of both sides:

x = 4

Therefore, the length of each side of the original cube is 4 yards.

5. Calculate the length of each side of the new cube:

Since the length of each side of the original cube is doubled, the length of each side of the new cube is 2 times the original length, which is 2 * 4 = 8 yards.

6. Find the volume of the new cube:

The volume of a cube is given by the length of one side cubed. So, the volume of the new cube is 8^3 = 512 cubic yards.

Therefore, the volume of the new cube is 512 cubic yards.
