Answer:
216
Step-by-step explanation:
Use geometric formulas to solve for each individual SIDE of the triangular prism
TOP and BOTTOM TRIANGLE sides:
<--- times 2 because we have TWO identical triangle sides
RIGHT RECTANGULAR side from our perpsective:
- LxW
- 8(7)
FRONT RECTANGULAR side:
- LxW
- 7(6)
BACK RECTANGULAR side:
- LxW
- 7(10)
Now you add all of those formulas together for your answer.
+
+ 8(7) + 7(10) + 7(6)
= 216
