Answer:
43.638 cubic meters
Explanation:
The triangular prism has 5 faces - 3 rectangular and 2 congruent triangular. Calculate the area of each face then add them together to find the surface area.
The triangles are 5.3 by 1.26 so the area of the two is 6.678.
The largest rectangle face is 5.3 by 3.3 so the area is 5.3*3.3 = 17.49.
The side rectangle face that is 3.3 by 3.6 so the area is 3.3*3.6 = 11.88.
The side rectangle face that is 2.3 by 3.3 so the area is 2.3*3.3 = 7.59.
Add all the areas together.
6.678 + 17.49 + 11.88 + 7.59 = 43. 638
