Question

How to find the surface area of triangular prisms ?

Answer 1

Answer:

To find the area of the rectangular sides, use the formula A = lw

To find the area of the triangular faces, use the formula A = 1/2bh,

Step-by-step explanation:

1st formula where A = area, l = length, and h = height.

2nd formula where A = area, b = base, and h = height.

Answer 2

To find the surface area of the triangular prisms, you need to use the following formula: A=2AB(a+b+c)h.

To find AB you use this formula:AB= square root of (s(s﹣a)(s﹣b)(s﹣c))

Substitute your values and you will be able to find your surface area.
