amistre I need help, attach fiele ,what is sutface Area of equalateral trinangle if a=6 , b=4 and sland heigh is 5
let me look at it some :)
surface area of the equi triangle..... isnt that just perimeter inthe picture? of is this a top view?
slant height tends to mean distance up the face of a side
surface Area= Ph+2B but for equalateral I don't know formular
for this picture 3 side equal I don't know how to find surface Area
this is a bottom view of what I think im looking at
yes surface Area triangle prism
can u help me how?
i can try to interpret this; the 'b' is the height of a face; and the 'a' is the base; so surface of 1 trianle = 6*4/2 = 12 and with 4 sides equal; we have 12*4 = 48 if I see it right
and the slant height means the distance of an edge; whih make it a normal 3-4-5 right tri
yes I know A =12 and time for 3 Triangle
4 trianlges; not 3 :) lateral area is 3 tris, total surface is 4 tris
opps; i think I assumed the base tho
since the bottom is 6x6x6 we know its angles are 60 degress
Ok I for got 3 onthe top and one in the bottom, then 12*4 is surface A of equlateral triangle?
the area of triangle can be determined by: side * side * sin(angle) ------------------ 2
the top are is 12 * 3 = 36 the base area = 18sin(60)
I see TY amistree
base is abt: 15.588....
youre welcome :)
yes
thank again
