Question

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

Explanation:

Step1: Recall cube - net properties

A cube net is a 2 - D shape that can be folded to form a 3 - D cube. A standard cube net has 6 square faces. Both of the given diagrams are valid cube nets as they are composed of 6 congruent square faces which can be folded to form a cube.

Step2: Recall surface - area formula for a cube

The surface - area formula of a cube with side length \(s\) is \(SA = 6s^{2}\). Given \(s = 27\) ft.

Step3: Calculate the surface area

Substitute \(s = 27\) into the formula: \(SA=6\times(27)^{2}=6\times729 = 4374\) square feet.

Answer:

4374
