Question

anonymous · Answer

i figured since a cube has 6 sides i would just divide 144 by 6 but none of my answers are 24

anonymous · Answer

lateral area is the the area of one of the faces ^.^

anonymous · Answer

and so is equal to the square of the side length haha

anonymous · Answer

anonymous · Answer

well I'm sure it's one of those ^.^

anonymous · Answer

how do i solve it

anonymous · Answer

like I said, the lateral area is the area of one of the faces of the cube.
now, the area is the square of the side-length

anonymous · Answer

let's give that side length a name, let's call it x ^.^
So $\large x^2 = 144$  since 144 is the area. so?

anonymous · Answer

based off that i would guess 12 is the answer cause 12^2 is 144

anonymous · Answer

was i supposed to solve it like that?
