The <em>xy</em>-plane has a normal vector of 〈0, 0, 1〉, and any plane parallel to it will have the same normal vector.
Then the equation of the plane through (6, 3, 2) that is parallel to the <em>xy</em>-plane has equation
〈<em>x</em> - 6, <em>y</em> - 3, <em>z</em> - 2〉 • 〈0, 0, 1〉 = 0
==> <em>z</em> - 2 = 0
==> <em>z</em> = 2
(5)(6)(8) = 240
240 blocks in one box.
(240)(3) = 720
720 blocks in three boxes
I’m not sure if you need the steps but x is -4 and y is -1
(4,1) can be taken out.
The input and output values cannot be the same.
Hope this helps!
