(Please Help Will mark brainliest) What is the total surface area of the triangular prism? 30m^2
60m^2
75m^2
63m^2

63m^2

Step-by-step explanation:

Find the area of each base

2.5(10)= 25

1.5(10) = 15

2(10) = 20

Add them together

20 + 15 + 25 = 60

Now find the area of the triangles at each side

2(1.5)(1/2) = 1.5

Since there are two triangles, multiply the area by 2

1.5(2) = 3

Add the areas together

60 + 3 = 63
