Answer:
The surface area of each part of the prism is 4.5 mm².
Explanation:
We are given that,
The parts produced are rectangular prisms.
Surface area of each part of the prism =
, where s= length of base and h= height.
Now, substituting s= 0.5 mm and h= 2 mm, we get,
Surface area of each part of the prism =

i.e. Surface area of each part of the prism =
= 4.5 mm²
Thus, the surface area of each part of the prism is 4.5 mm².
