Right Triangle Prism

563blackghost · Answer

Correct ^^ It is a triangular prism...now what is the formula for the surface area of a triangular prism?

anonymous · Answer

S=Width*Length*Height

563blackghost · Answer

Correct ^^ It is $\Large\color{green}{SA=wh+lw+lh+ls}$

563blackghost · Answer

you did put this up right after you deleted your last post?

anonymous · Answer

Yeah, I thought I was wrong.

563blackghost · Answer

Well you are correct ^^ there are many different forms to find the surface area ^^

563blackghost · Answer

So with that know we solve...we first input the side, width, length, and height to find the surface area....

$\Large{S=5cm,~W=4cm,~H=3cm,~and~L=11cm}$

So we input this into the equation....

$\LARGE\color{crimson}{SA=4(3)+11(4)+11(3)+11(5)}$

1,600cm?

563blackghost · Answer

Incorrect....

Simplified equation:

$\LARGE\color{purple}{SA=12+44+33+55}$

anonymous · Answer

144cm^3?

563blackghost · Answer

Correct ^^ So it would be $\Huge\color{red}{144cm^{2}:)}$
