Idk how to find the surface area of this triangular prism

you have to find the area of the rectangle at the bottom and then find the area of the 2 long triangles and the 2 small triangles and add them together

Step-by-step explanation:

1/2 bxh - b = base h = height

so 8cm (height) × 26cm (base) × 12cm (also base) = something something × 1/2 = answer...or ÷ 1/2 I forgot but its something like that I think. bruh just ask whoever's in the house lol

u bout ugly as   a mf

step-by-step explanation: lol

126 maybe. sorry
