Answer:

360cm squared

Step-by-step explanation:

Surface area is where you add all the sides area together.

10 multiplied by 13 is 130

10 multiplied by 12 is 120

12 multiplied by 5 is 60

60 divided by 2 is 30

2 lots of 30 is 60

5 multiplied by 10 is 50

130 add 120 add 60 add 50 is 360cm squared

Given:

  • Triangular prism

To find:

The surface area of the given triangular prism.

Solution:

[tex]sa = bh + ( b_{1} + b_{2} + b_{3})l[/tex]

[tex]sa = 12(5) + (5 + 12 + 13) \times 10[/tex]

[tex]sa = 60 + (30)(10)[/tex]

[tex]sa = 60 + 300[/tex]

[tex]sa = 360 \: {m}^{2} [/tex]

Hence, the surface area of the given triangular prism is 360 square meters.
