wait no ignore that
dont click on it
What do you think the answer is?
wait the area is 2 bh x wl or something like that?
well solve that then
so it is that? formula
so 6x 10 x 9 x 8 ? i dont know HELP!
One sec I have to find the formula
Do you know what kind of prism is this?
am i right?
Let me tag some people
i just need to know where the base height width and length is and how to times it.
I dont't know the formula
there are 5 faces. the triangle face closest to us is a right triangle. can you find its area using 1/2 base * height ?
is the base byd and the hieght 10yd?
you want the bottom line that goes sides and the line that goes straight up (not the hypotenuse)
so, 8yd and 10yd?
8 goes straight up. which line goes sideways?
you want the "legs" that form the right angle (see the little square in the corner?)
yes i see it
what are the lengths of those two legs?
9 and 8?
6= base hieght = 8
now can you find its area ?
6 x 8 x 2 = 96 / 2 = 48
why did you put in the extra 2 ?
cuz sometimes when people like teach me they put in the 2 and then im like well i should do that for everything now.
Let's go slow and find the area of just the one face, the triangle with base 6 and height 8 the formula is 1/2 * base * height what do you get ?
base * height is 6*8 = 48 but now multiply by 1/2
48 times 1/2 means 48/2 (it is not 96)
oh, then 24
yes. next the "back triangle" is the same area, it is also 24 so the front and back add up to 24+24= 48 now we have to find the area of the 3 rectangle shaped faces.
k do we do 48 x 3?
I see a 9 x 10
you are looking at a rectangle and the opposite sides of a rectangle are equal what is the length of the red line in the figure?
6 but then im thinking it might be 8
do you see you are looking at |dw:1433368988335:dw|
the opposite sides are equal. it is not 8
yes, 9 can you find the area of the rectangle with sides 6 and 9 ?
you already figured out the bottom red line is 9 can you figure out the area of that rectangle ?
24+24 + 90 + 54 = 192
yes, but we need the last face
add that to 192
192 is not the whole answer yes 72 for the last face
ok, there should be a choice with 264. Pick it!
@phi can you help me
I will! Thank you so much for helping me!!!!!
