Answer:

The surface area of the prism is 96 square units

Step-by-step explanation:

First we need to calculate the area of ​​the triangle

a = area of triangle

a = (6  * 2 ) / 2

a = 12 / 2

a = 24

Now we have to calculate the 3 areas of the rectangles

a1 = 7 * 3

a1 = 21

a2 = 7 * 6

a2 = 42

a3 = 7 * 3

a3 = 21

Now we must add all the calculated areas and the triangle 2 times

a1 + a2 + a3 + 2a =

21 + 42 + 21 + 2 * 6

21 + 42 + 21 + 12 = 96

96

The surface area of the prism is 96 square units
