Answer 1

pls heelp

Answer 2

pls help @pooja195

Answer 3

well do you know what a cross section is?

Answer 4

my teacher never explains it, and if i ask her she just says "well u shouldve paid attention!" yet all she does is hand out the homework and play crossword puzzels all day

Answer 5

i personally dont like teachers like that i know how you feel ok so a cross section is a surface or shape that is or would be exposed by making a straight cut through something, especially at right angles to an axis.-google

Answer 6

if you cut down a middle of a cube what shape will u see?

Answer 7

a rectangle? since its cut down the middle its not as wide, but if u cut it down a corner you get a triangle right?

Answer 8

we are talking about directly down the middle it is not a triangle or a rectangle nice try :) what can it be?

Answer 9

another cube?

Answer 10

okay right but if u were to look at the surface what shape would it be??

Answer 11

a square

Answer 12

yay! well done! it is indeed a square :D

Answer 13

:D

Answer 14

im glad u got it :) do u get it a little better now?

Answer 15

yes because if u cut it down between the numbers given, its a square! so it would be c.w

Answer 16

the diagonal from 2 to 7 is longer than the length from 1 to 2

so that means we have a rectangle (not a square)

Answer 17

hmm i thought it would be a square =/

Answer 18

ohh yea :/ @jim_thompson5910 is right, it was a rectangle. thanks for your guys' help i appreciate it, and it does make sense because down the middle it is a square (thus being one of its faces) but diagonally its longer so its a rectangle.

Answer 19

right so you were correct sorry about the mistake hope your not lost lol

Answer 20
