Answer 3

Based on my calculations I though it was 13 units

Answer 4

thought not though

Answer 5

Formula for the area of a triangle is 1/2bh. Do you have any diagrams for this?

IF not then I'll assum it will look like this:

First thing you have to do is find the length of of the base, which is the length of AB
Then find the height/altitude, which is the length of CD
Calculate the lengths using the distance formula.

Then after you find the value, apply the the formula for the area.
Give me a sec. I'll try to solve it also and I'll tell you if we get the same thing.

Answer 6

OK thanks. I just keep getting the same result...

Answer 7

I get a different answer. hmm.. can you tell me what did you get for the length of AB?

Answer 8

I just calculated the triangle and multiplied the volume against the length of it and I keep getting the same result.@Data_LG2

@Data_LG2 I suck at math AND I AM SHERLOCK HOLMES FOR CRYING OUT LOUD

Answer 10

i REALLY WISH SOMEONE WOULD ANSWER! I feel like I am in the math-twilight zone :(:::::

Answer 11

sorry late response..

do you know the distance formula?

Answer 12

Sort of...
