which diagram is a net for the cube? what is the surface area of the cube? square centimeters
Answer
Explanation:
Step1: Recall cube - net property
A cube net should be able to fold into a cube. Both of the given diagrams are valid nets for a cube as they are composed of 6 congruent squares which can be folded to form a cube.
Step2: Recall surface - area formula
The surface - area formula of a cube is $S = 6a^{2}$, where $a$ is the side - length of the cube. Here, $a = 5$ cm.
Step3: Calculate surface area
Substitute $a = 5$ into the formula: $S=6\times5^{2}=6\times25 = 150$ square centimeters.
Answer:
150
