Question

what is the surface area of the cube? 27 ft. 27 ft. 27 ft. square feet

Explanation:

Step1: Recall surface - area formula

The surface - area formula of a cube is $S = 6a^{2}$, where $a$ is the side - length of the cube.

Step2: Identify side - length

The side - length $a = 27$ ft.

Step3: Calculate surface area

Substitute $a = 27$ into the formula: $S=6\times27^{2}=6\times729 = 4374$ square feet.

Answer:

4374
