Question

(Please Help Will mark brainliest) What is the total surface area of the triangular prism?

Answer 1

Answer:

63

Step-by-step explanation:

Atotal= Area of base + Area of lateral= 60+3 =63

2 Area of base = 2 ( 1/2 b h )

= 2( 1/2 2x 1.5 )

= 2( 1.5 )

= 3

3 Area of lateral = 3 bh = 2.5X10 +2X10 +1.5X10 = 25+20+15 = 60

Answer 2

Answer:

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
