Question

The lateral area of a cube is one hundred forty-four square kilometers. What is its side length?

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

the answers are 3km, 6km, 12km, 18km

Answer 5

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

Answer 6

how do i solve it

Answer 7

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

Answer 8

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

Answer 9

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

Answer 10
