OpenStudy (anonymous):

option D 1680 cm3

OpenStudy (anonymous):

volume = 12*20*7 = 1680 good luck :P

OpenStudy (anonymous):

wait

OpenStudy (anonymous):

Can you help me whith a few more plz will give medal and fan

OpenStudy (anonymous):

I'll try my best :P

OpenStudy (anonymous):

is any other data given??

OpenStudy (anonymous):

oh sry that was 60

OpenStudy (anonymous):

but on this one im stuck big time

OpenStudy (anonymous):

well i can see only the options and the words *find the volume of the prism*

yes

OpenStudy (anonymous):

well in that case it is 94 cm2 if values are in centimeters!!

OpenStudy (anonymous):

:P if in inches jus put in2

OpenStudy (anonymous):
