Hi my dear friend,
Answer:
294
square centimeters
Step-by-step explanation:
We know that a cube has 6 faces of equal area. What will the area of one face be?
In a cube, the length and width are the same, so both sides will be7cm, yielding an area of 49square centimeters.
This is the area of one side, so to find the surface area, we multiply this by the number of sides (6). We get 49cm2⋅
6=294cm2
The surface area of a 7cm cube will be 294
~Thank you
