Answer:
The surface area of the prism is 96 square units
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
