Question

The lateral area of a cube is 576 square kilometers. What is its side length?

A. 36 km
B. 12 km
C. 6 km
D. 24 km

Answer 1

Lateral surface area:

LSA = 4s^2

576 = 4s^2

From here, solve for s to find your answer.

Answer 2

how? do i put one of the choices and then see if it equals 576?

Answer 3

you can do that, or you can divide both sides by 4, then take the square root of both sides to isolate s

Answer 4

is it C?

Answer 5

how did you get C

Answer 6

4s^2
4 x 6^2
24^2
24 x 24
576

Answer 7

no, using PEMDAS, 4 x 6^2 is 4 x 36 = 144 and not 576
