Question

How do you find the surface area of this triangular prism?

Answer 1

To find the area of a triangular prism you have to do A 1/2 bh or A bh/2 which means you have to multiply those two fractions and reduce them

Answer 2

Answer:

Find the area of the 2 triangle faces first and then find the area of the 3 rectangle faces and add them together to get $159cm^{2}$

Step-by-step explanation:

Step 1: Find the surface area of the 2 triangles

$\frac{(6)(5.5)}{2}$ x2 = $33cm^2$

Step 2: Find the surface area of the 3 rectangles

(6x7) x 3 = $126cm^2$

Step 3: Add the 2 surface areas together

$33cm^2$ + $126cm^2$ = $159cm^2$

Therefore the surface area of the prism is $159cm^{2}$
