The image shows a cube with side lengths of 7 yards, and the question asks for the surface area of the cube.

The formula for the surface area of a cube is:

$\text{Surface Area} = 6 \times s^2$

Where $s$ is the length of one side of the cube.

Given $s = 7$ yards:

$\text{Surface Area} = 6 \times (7^2) = 6 \times 49 = 294 \, \text{square yards}$

So, the surface area of the cube is 294 square yards.
