working out?
OpenStudy (anonymous):

378+30=408
OpenStudy (anonymous):

can u help me with that question
OpenStudy (anonymous):
volume=1/2*length*width*height
OpenStudy (anonymous):
so
V= 1/2*(5)*(6)*(21)
V=315cm^3
OpenStudy (anonymous):
nice
OpenStudy (anonymous):
okay man love ya cuz for helping me out

after u get the answer can u write it altogether because getting kinda confused thnx
OpenStudy (anonymous):
V=203472cm^3
OpenStudy (anonymous):
okay
OpenStudy (anonymous):
V=3.14*.6^2*1800
V=2034.72m^3
2034.72m^3*100=203472cm^3
OpenStudy (anonymous):
okay.
