Ok, the same as before. The equation is for a traingular prism.
\[V = \frac{ a }{ 2 } \times 8 \times 5\]
OpenStudy (unanimoose):
Where a = 12, c = 8 and h = 5.
OpenStudy (unanimoose):
Woops, I meant to put c and h but I guess I did that for you, hehe.
OpenStudy (sierra!):
so how do i do that

Replace a with 12, divide them and then multiply the values.
OpenStudy (sierra!):
so D
OpenStudy (sierra!):
i have one more this looks confusing

Not quite, you forgot to divide 12 and 2~

For the other one tho, you didn't do 12/2. You came out with double what you wanted.
OpenStudy (unanimoose):
12/2 = 6
6*5*8 = 240
OpenStudy (unanimoose):
But anyway, attach the image to for this one. ^^
OpenStudy (sierra!):
so 240
OpenStudy (unanimoose):
Yeah.
