Question

I need help pleaseeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

Answer 1

360cm squared

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

Answer 2

Given:

• Triangular prism

To find:

The surface area of the given triangular prism.

Solution:

`sa = bh + ( b_(1) + b_(2) + b_(3))l`

`sa = 12(5) + (5 + 12 + 13) * 10`

`sa = 60 + (30)(10)`

`sa = 60 + 300`

`sa = 360 \: {m}^(2)`

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