The surface area of the triangular prism is calculated as: 153 cm²

<h3>How to Find the Surface Area of a Triangular Prism?</h3>

The net of a triangular consists of 2 identical triangular faces, and three different rectangular faces. Given the net of a triangular prism, to find the surface area, find the area of each given shape that makes up the net of the triangular prism.

Surface area of the triangular prism = 2(area of triangular base) + area of the 3 different rectangular faces.

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

Base (b) = 6 cm

Height (h) = 3 cm

Area of the 2 triangular faces = 2[1/2(6)(3)]

Area of the 2 triangular faces = 18 cm²

Area of the larger rectangular face:

Area = (length)(width) = (9)(6)

Area of larger rectangular face = 54 cm²

Area of the medium-sized rectangular face:

Area = (length)(width) = (9)(5)

Area of medium-sized rectangular face = 45 cm²

Area of the smaller rectangular face:

Area = (length)(width) = (9)(4)

Area of smaller rectangular face = 36 cm²

Surface area of the triangular prism = 18 + 54 + 45 + 36

Surface area of the triangular prism = 153 cm²

If you have a 5 letters A,B,C,D,E and you can put them in any order how many ways can you place them
IceJOKER [234]

The first letter can be any one of 5.  For each of those . . .
The second letter can be any one of the remaining 4.  For each of those . . .
The third letter can be any one of the remaining 3.  For each of those . . .
The fourth letter can be any one of the remaining 2.  For either of those . . .
The fifth letter is the last remaining one.

  Total number of possibilities = (5 x 4 x 3 x 2 x 1)  = 

                                                          <em> 120 ways</em> to line them up.

Now, may I say that being a hater of school is not something that
makes you cool.  Maybe it does make you one of the crowd, but life
is not a war between you and school.  School is simply something that
a lot of grown-ups spend a lot of money on, and a lot of teachers spend
their whole life on, to make sure that a lot of kids won't go through <em><u>their</u></em>
whole life stupid.  You can learn everything you ever want to know there,
and it's all free.  That's a pretty good deal.
