Question

what is the wedge that could be determined by the coordinates (0,0,0,), (a,0,0), (0,b,0), (0,0,c)

a) Determine the area A(x) of a vertical cross section.

b) Determine the vloume of the solid

Answer 1

(Hint: use similar triangles and the fact that the area of a triangle is 1
2baseheight

Answer 2

you able to get the cross section area ?

Answer 3

you guys can download the attachment for more info

Answer 4

I do not think so

Answer 5

a) start with computing base or height of the cross section triangle first
b) for volume, just take the integral of A(x) derived above

Answer 6

how do I compute them though

Answer 7

lets start with height

Answer 8

height is in XZ plane right. can you see two similar triangles ?

Answer 9

yes

Answer 10

mid line is the cross section..

Answer 11

u getting any clues yet ?

Answer 12

no

Answer 13

ok.. its tricky

Answer 14

lets say center to cross section distance is x
