Question

100 points. Find the surface area of the triangular prism. The unit is cm^2

Answer 1

Answer:

1380

Step-by-step explanation:

Answer 2

First we find the area of the two triangles on each side (keep in mind that they are equal/congruent to each other):

(24*10)/2 = 120 cm^2

Then you find the areas of the three rectangles that are left:

24*19 = 456 cm^2
26*19 = 494 cm^2
10*19 = 190 cm^2

Finally, to find the surface area of the prism:

120+120+456+494+190 = 1,380 cm^2
