u have florida virtual dont u

OpenStudy (anonymous):

No I hsve algebra 2

OpenStudy (anonymous):

Have

OpenStudy (aravindg):

what is the area of one side?

OpenStudy (anonymous):

X+5

OpenStudy (aravindg):

nope thats the side

OpenStudy (anonymous):

How do you get the area of one side??

OpenStudy (aravindg):

area of one side will be the side squared because cube consists of square faces

OpenStudy (anonymous):

The area of one side is x^2+25

OpenStudy (aravindg):

NOPE

OpenStudy (aravindg):

area will be (x+5)(x+5)

OpenStudy (aravindg):

now find Total surface area

OpenStudy (anonymous):

Yess that is x squared +25

OpenStudy (anonymous):

Do I just times that by 6 now??

OpenStudy (aravindg):

no

OpenStudy (aravindg):

(a+b)(a+b)=a^2+2ab+b^2

OpenStudy (anonymous):

So the area is X^2+10X+25

OpenStudy (anonymous):

Now do I multiply that by 6
