The first thing we will do is assume that the prism is square based. We have then that the edges of the base are: P = 4L P = 4 (8) P = 32 cm The edges of the top of the prism are: P = 4L P = 4 (8) P = 32 cm The edges of the prism height are: P = 4h P = 4 (11) P = 44 cm The total sum will be: Pt = 32 + 32 + 44 Pt = 108 cm Answer: the sum of all edges is: Pt = 108 cm
