Question

1] The lateral area of a cube is 256 square kilometers. What is its side length?

a] 4 km
b] 8km
c] 24 km
d] 32 km

Answer 1

side length = sqrt 256 = 16

Answer 2

thats a large cube!!!!

Answer 3

how could it be 16?

Answer 4

That sure is a big cube....:-)

"Lateral" usually means excluding the "base", did u mean surface area?

Answer 5

if area = 256 and its a square then the side = sqrt 256 = 16

Answer 6

6 sides (5 excluding the "base")

Answer 7

oh - i assumed lateral meant one of the faces of the cube

Answer 8

Normally, if u say "lateral" area, it means excluding the base, like in a pyramid.

Answer 9

oh ok

Answer 10

It's a bit strange with a cube, though.

Answer 11

Anyway, we can do it with 5 or 6 sides...

Answer 12

so area of 5 sides = 256 ?

Answer 13

yahoo answers says lateral area of a cube is 4(!) sides. who knew?

Answer 14

lol

Answer 15

Yes, I have never heard this expression used for a cube before.

Answer 16

well that would fit with 8 then

Answer 17

i am not in any way endorsing this answer. caveat emptor

Answer 18

Let's do it with 4, 5 and 6, op can choose one...

Answer 19

6 is sqrt 44

Answer 20

kilometres!

Answer 21

i suppose it is 4 - the top side isn't lateral i guess

Answer 22

But which is the "top"?

Answer 23

yes - kilometres lol

Answer 24

or the bottom for that matter

Answer 25

well - the horizontal one - the others are vertical - i dont know really - just looking for possibilities

Answer 26

It seems to me u cannot arbitrarily exclude 1 or 2 sides or even assume a position/orientation.

Answer 27

Assume it is balanced on a corner...

Answer 28

yes - i agree

Answer 29

Floating in free space.

I have convinced myself that op really meant surface area since lateral area has no meaning.

Answer 30

i cant get over its size - must be an alien artifact!!

Answer 31

Actually I have convinced myself that whoever posed this question has assumed that lateral means something else.

Answer 32

According to the choices, it must be 8 although I don't agree and think it is a crap question.

Answer 33

if it is surface area then one face = 32

Answer 34

yea

Answer 35

side = x, 6 sides of x^2

Answer 36

Or 4 possibly:-)

Answer 37

oh aye !! - sorry

Answer 38
