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 1: Find the surface area of the 2 triangles

((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)

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
