Step-by-step explanation:
Explanation:
Because this is a cube, it's helpful to remember that the value of the diagonal of one face is the same length for the other five faces. Additionally, the length of one edge will be the same length of all the cube's other edges. This helps relieve the stress of there being more than one possible right answer.
Correct answer:
2cm
Explanation:
The surface area of a cube can be represented as 6s2, since a cube has six sides and the surface area of each side is represented by its length multiplied by its width, which for a cube is s2, since all of its edges are the same length.
We can substitute 24cm2 into this equation and then solve for a:
SA=6s2
24=6a2
4=a2
a=2
So, one edge of this cube is 2cm in length.
