Regular quadrilateral prism has an altitude h = 11 cm and base edges b=8 cm. Find the sum of all edges.
natka813 [3]
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
