The equation of a plane in space is x + 3y + 2z = 6.
1.) The three planes of the axes and the plane you have sketched create a triangular pyramid. Find the volume of this pyramid, showing the formula you are using and all
calculations below.
For my intercepts I got values of, (6, 2, 3), with x = 6, y = 2, and z = 3. I plotted these intercepts on the graph.
How would I do part B of this problem (finding the volume)?

Best ResponseYou've already chosen the best response.0OK i now see that you have just presented your intercepts differently/ unconventionally [as if they were one] the next step is to integrate \(\large \int \int z(x,y) \ dA = \int \int 3  \frac{x}{2}  \frac{3y}{2} \ dx \ dy\) which is either: \(\large \int_{y=0}^{2} \int_{x = 0}^{6  3y} 3  \frac{x}{2}  \frac{3y}{2} \ dx \ dy\) or \(\large \int_{x=0}^{6} \int_{y = 0}^{2 \frac{x}{3}} 3  \frac{x}{2}  \frac{3y}{2} \ dy \ dx\) i get 6.

Best ResponseYou've already chosen the best response.0@Irishboy123 If I'm going to be quite honest with you... I have no idea what most of that means. I'm taking a geometry course as a sophomore in high school. Could you explain that set of equations to me in a simpler way?

Best ResponseYou've already chosen the best response.0Would this be the correct equation, then? \[\frac{ 1 }{ 3 } (6) (3) = 6\]

Best ResponseYou've already chosen the best response.0Assuming that my calculation of 6 equaling the base area is correct.
