How to find total surface area for a triangular prism

bh + 3lw

Step-by-step explanation:

A triangular prism is made up of two opposite rectangular surface, two opposite triangular surfaces and its rectangular base.

Area of a triangle = bh

where b is its base, and h is the height.

Total surface area of the two triangular surfaces = bh + bh

                                                     = bh

Area of rectangle = lw

where l is the length and w its width.

The surface area of the rectangles = lw + lw + lw

                                                       = 3lw

Thus,

Total surface area for a triangular prism = bh + 3lw

725 parts per hour.

step-by-step explanation:

hi there, this answer is actually really simple.

you can set it up as 1450/2 or 3625/5 to find the answer.

they want to know how much per hour is being made, so you just divide.

1450/2=725.

and that's how many are produced per hour.

hope this . : )
