a prism wouldn't have an area it would have a volume. Area is flat, volume is 3 dimensional.
for a prism we use V=A x h
volume = area of the base x height
To find the area of the base, we simply use A=l x w (area=length x width)
So in your example V= (3 x .5) x 12 [note: 1/2 is the same as .5]
I'll let you do this math but if you want to check that you know how then let's just try this.
if the base is 4 inches and 3/4 inches and the height is 14 inches.
V=(4 x .75) x 14
V= 3 x 14
V= 42 cubic inches
it's cubic inches because it's 3 dimensional (cubic) and we are working in inches (inches)
add: it's possible to help with homework without actually doing it for someone. That'd be a good skill for everyone to learn. Thanks for the oppertunity to practice teaching math. :-)
nice try but i am not doing ur homework
thx 4 the points
