Given that the cubical piece has side (s) 7 mm, and a cylindrical hole of diameter (d) as 3 mm.
The volume of the piece can be calculated as,

It is mentioned that the material costs $207 per cubic meter, so the cost (c) of 1 piece is calculated as,

This is the cost (in dollars) for 1 piece.
Given that the manufacturer wants to produce 1,000,000 such pieces, so the total cost (TC) is calculated as,

Thus, the total prototypes will cost around $60.75
Answer:
No, because 3 x 7 = 21 - 4 = 17

a) n (No. of peoples) = 50
r (No. of prizes) = 3
p(n,r) = p (50,3)

b) n(No. of players)=14
r (No. of players for Batting)=9

c)n(Total applicants)=30
r(tester positions)=4
They equal 5*5=25 and 35*35=1225
