Answer:

216

Explanation:

Use geometric formulas to solve for each individual SIDE of the triangular prism

TOP and BOTTOM TRIANGLE sides:


  • (ab)/(2)

  • (6(8))/(2) <--- 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.


(6(8))/(2) +
(6(8))/(2) + 8(7) + 7(10) + 7(6)

= 216
