which diagram is a net for the cube? what is the surface area of the cube? square feet
Answer
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 given diagrams are valid nets for a cube as they are made up of 6 congruent square faces which can be folded to form a cube.
Step2: Recall surface - area formula
The surface - area formula for a cube is $SA = 6s^{2}$, where $s$ is the side - length of the cube. Here, $s = 7$ ft.
Step3: Calculate surface area
Substitute $s = 7$ into the formula: $SA=6\times7^{2}=6\times49 = 294$ square feet.
Answer:
294
