Answer:

D

Explanation:

The front and back side area are
(3*2)/(2) which is 6. The left side is 3*10, which is 30. The bottom side is 4*10, which is 40 and the right side is 5*10 which is 50. So the equation is 6+6+30+40+50, which is D.

Answer:

D. 6 + 6 + 30 + 40 + 50 = 132

Surface area of triangular prism:

(perimeter of base) × length + base × height

(s₁ + s₂ + s₃)(l) + bh

Here, provided with:

  • s₁ = 3
    s₂ = 4
    s₃ = 5
  • l = 10
  • b = 4
  • h = 3

So, the surface area:


area: \sf (3+4+5)(10) + (4)(3) =(12)(10)+12 = 132

Only option D gives 132 as an answer which is equivalent to the area.
