Answer 4

thank you im new here can you help me?

Answer 5

To find the surface area of a triangular prism we would use this equation....\[SA = wh + lw+lh+ls\]

so

w=19
h=23
l=38
s=30

so we would input this into the equation....\[SA=19(23)+38(19)+38(23)+38(30)\]now we would solve ^^

Answer 6

im still quite confused

well with the whole thing im bad at paying attention and class or i might have missed a day where they explained this so everything is kinda making me lost.....you dont have to help me if you dont want ill try to figure it out

Answer 10

I can help ^^...can you please tell me what you know about finding areas?

Answer 11

i know you have to find at least two of the sides lengths...or i got that confused with perimeter hmmm or find the total of width and length and times it by two i doubt i got that right....

Answer 12

Well you are kind of correct... To find area alone for a square or rectangle we would multiply the two side lengths but with triangles you would multiply the two side lengths but you would then divide by 2... these are the three main ways to find the area alone....

Answer 13

thats a little more understanding i might have got it im not a hundred percent sure 3173 mm2 is that right...?

Answer 14

That is correct ^^

Answer 15

haha awesome thank you for helping me n.n
