Question

What is the total surface area??

Answer 1

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
