Question

which diagram is a net for the cube? what is the surface area of the cube? square feet

Explanation:

Step1: Recall surface - area formula for cube

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

Step2: Identify the side - length

Given that $a = 23$ ft.

Step3: Calculate the surface area

Substitute $a = 23$ into the formula: $S=6\times(23)^{2}=6\times529 = 3174$ square feet.

Answer:

3174
