We are given a cube of side 3 ft and we are asked to determine its surface area. The surface area of a cube is 6 times the area of one of its faces. The area of its faces is the side squared, therefore, the total surface area is:


S=6l^2

Where:


l=\text{ length of the side }

Now, we plug in the value of the side:


S=6(3ft)^2

Solving the operations:


S=54ft^2

Therefore, the surface area is 54 square feet.
