Find the surface area of the triangular prism shown below.

195.67 units²

Step-by-step explanation:

Formula for the surface area of the base:

Since we need to find the area of 2 bases, we can simplify the expression to just b*h

6*4=24

The area of the 2 bases is 64 units².

Now we need to find the area of the lateral faces:

(5*7)+(6*7)+(7.81*7)=

35+42+54.67=131.67

The lateral surface area is 131.67 units².

Now we need to add the bases and the lateral surface area for the total surface area.

131.67+64=195.67

The total surface area is 195.67 units²

answer:

your answer is: c. 196 7/8 in^3.
