find the surface area

OpenStudy (anonymous):

you know how to find the surface area @steffie84 ???

OpenStudy (anonymous):

no

OpenStudy (anonymous):

surface area = 2lw+2hw+2hl

OpenStudy (anonymous):

length= l width= w height= h

OpenStudy (anonymous):

518

OpenStudy (anonymous):

@kliedako what would be my next step?

OpenStudy (anonymous):

okay, since the unit is already in square inch

OpenStudy (anonymous):

8c/ Sq.in * 518 Sq. in = ?

OpenStudy (anonymous):

647.5

OpenStudy (anonymous):

no

OpenStudy (anonymous):

518 x 8 that would be the answer, since you can cancel the sq. in

OpenStudy (anonymous):

4144

OpenStudy (anonymous):

yea

OpenStudy (anonymous):

I was on right track just the wrong way I did it

OpenStudy (anonymous):
