Answer:
excuses me I don't have point to ask questions so I write a thing instead of answering ❤
A linear equation is RISE over RUN (y/x) so the starting point would be -6 and from there its a straight line across
1,655,000 maybe I not entirely sure sorry
Volume = (Area of the base)x(Height)
66.85 = 15(H)
66.85/15 = H
H = 4.4567
The height is 4.4567mm.
