How do i find surface area of a triangler prisim

A triangular prism has three rectangular sides and two triangular faces. To find the area of the rectangular sides, use the formula A = lw, where A = area, l = length, and h = height. To find the area of the triangular faces, use the formula A = 1/2bh, where A = area, b = base, and h = height.

Hope it helps..

Have a great day : P

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
