Question

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

Explanation:

Step1: Recall cube - net property

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

Step2: Recall surface - area formula

The surface - area formula of a cube is $SA = 6s^{2}$, where $s$ is the side - length of the cube. Given $s = 5$ cm.

Step3: Calculate surface area

Substitute $s = 5$ into the formula: $SA=6\times5^{2}=6\times25 = 150$ square centimeters.

Answer:

150
