Answer:


54 \: {ft}^(2)

Explanation:

The surface area is the sum of the lateral and base areas

Since the given figure is a cube (all sides and walls of a cube are equal), instead of finding its surface area the harder way, we can find the area of one side and multiply it by the number of sides a cube has (which is 6):


a(surface) = 3 * 3 * 6 = 54 \: {ft}^(2)
