Question

A length of copper piping is in the shape of a triangular prism. The
triangle on it’s end is 9mm tall, 4mm wide. The piece of pipe is 18cm long.
What is the surface area of the pipe?

Answer 1

Answer:

you can solve it using formula

2( lb+by+hl)

Answer 2

Answer:

Step-by-step explanation:

Area of Triangles = (9 x 4) ÷ 2

              = 18mm2

      = 18 x 2

      = 36mm^2

Front Rectangle   = 180 x 10

                  = 1800mm^2

Back Rectangle    = 180 x 9

                  = 1620mm^2

Total Surface Area = 36 + 1800 + 1620 + 720

                    = 4176mm^2

Base Rectangle    = 180 x 4

                  = 720mm2
