Question

What is the total surface area??

Answer 1

Answer:

216

Step-by-step explanation:

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

TOP and BOTTOM TRIANGLE sides:

• $\frac{ab}{2}$
• $\frac{6(8)}{2}$  <--- 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.

$\frac{6(8)}{2}$ + $\frac{6(8)}{2}$ + 8(7)  + 7(10) + 7(6)

= 216
