hold on a sec
Vocaloid (vocaloid):
ok the volume of a prism is V = l*w*h = b*h, where b is the area of the base and h is the height, does that help?
OpenStudy (anonymous):
a little...im gonna try solving it
OpenStudy (anonymous):
couldnt i do 120*5 and get the answer of 600 square feet. ??
Vocaloid (vocaloid):
@blondie$$$ Yup, you got it!

Vocaloid (vocaloid):
capacity = volume = l*w*h
OpenStudy (anonymous):
ok, so 9*9*9
Vocaloid (vocaloid):
yea
OpenStudy (anonymous):
k so the answer is 729?! :)
Vocaloid (vocaloid):
yes

Yaaa!! thanks so much!
OpenStudy (anonymous):
can i ask you something else? i have got an answer but idk if its correct
Vocaloid (vocaloid):
sure
OpenStudy (anonymous):
ok...so the question is What is the volume of the cylinder?
OpenStudy (anonymous):
ok, the cube has a length of 18ft. and a height of 7 ft....i got the answer of 126pi ft. cubed

Vocaloid (vocaloid):
wait what, this problem doesn't make sense
if it's a cube, then the length, width, and height should be equal
and where are you getting pi from?
OpenStudy (anonymous):
here...ill try to show you...
Question 4.4. What is the volume of the cylinder?
(Points : 4)
126 ft3
252 ft3
882 ft3
2268 ft3
OpenStudy (anonymous):
thats the question...but in between the numbers and ft there is a pi sign
OpenStudy (anonymous):
can you still help me?
OpenStudy (anonymous):
and its a cylinder

OpenStudy (anonymous):
my bad...i must have said cube...im so sorry
Vocaloid (vocaloid):
volume of a cylinder: pi*r^2*h
OpenStudy (anonymous):
so is the answer 126 in?
Vocaloid (vocaloid):
is the radius 18?
OpenStudy (anonymous):
yes

Vocaloid (vocaloid):
try again, you've almost got it
Vocaloid (vocaloid):
remember the exponent
OpenStudy (anonymous):
oh right...so its going to be 252??
Vocaloid (vocaloid):
nope.
V = pi*r^2*h = pi*18*18*7
Vocaloid (vocaloid):
r^2 = r*r

OpenStudy (anonymous):
k so its 2268 right?
Vocaloid (vocaloid):
yea
Vocaloid (vocaloid):
just as a tip, if you ever need the formula for the volume/surface area, you can always look it up on google to save you some time :)
OpenStudy (anonymous):
ok, thanks!!! :)
Vocaloid (vocaloid):
are there any other problems you need help with?
