Volume of a Pyramid

Question

Find the volume of a pyramid given its height is 138.8m and its base is 230.4m along the side

 

use the formula:           | x1  y1  z1  1|

                                      | x2  y2  z2  1|

                       1/6 det  | x3  y3  z3   1|

                                      | x4  y4  z4  1|

 

where (x1,y1,z1)..... are points

 

Answer 1

Place the bas with a corner at the origin and two of the sides on x/y axis. Then find the points of each corner and height i.e.

(240.3,0,0), (0,240.3,0), (240.3,240.3,0) and then find the height point. Then take the determinant you have with those 4 points.
