jimthompson5910 (jim_thompson5910):

you are correct needmathhelp7, don't forget to use the proper units

OpenStudy (anonymous):

Thank you! would it be 54 units? Or like sq. or cubed? No, right?

jimthompson5910 (jim_thompson5910):

units (without squared, cubed, etc) refers to length

jimthompson5910 (jim_thompson5910):

but you want area

OpenStudy (anonymous):

so it's just units :)

jimthompson5910 (jim_thompson5910):

no

jimthompson5910 (jim_thompson5910):

units are used for length square units are used for area cubic units are used for volume

jimthompson5910 (jim_thompson5910):

more concrete example inches = length square inches = area cubic inches = volume

Ooohhh okay got it thanks again Jim!! :D
