Question

What is the surface area of the Triangular prism? Pls answer ASAP I WILL GIVE BRAINLIEAST.

Answer 1

170cm²

Explanation:

so the middle rectangle part first

15x10=150

then there's triangles so i'm gonna skip the divided by 2 part.

5x4=20

150+20=170

Answer 2

Note that:

• Surface area = 2(Area of triangle) + 3(Area of rectangle)

Finding the area of triangle:

• Area of triangle = 1/2 x 4 x 5
• => Area of triangle = 1/2 x 20
• Area of triangle = 10 cm²

Finding the area of rectangle:

• Area of rectangle = 5 x 10
• => Area of rectangle = 50 cm²

Using the formula of surface area:

• Surface area = 2(Area of triangle) + 3(Area of rectangle)
• => Surface area = 2(10) + 3(50)
• => Surface area = 20 + 150
• => Surface area = 170 cm²
