Answer:
square root of (27)...which is 5.2"
Step-by-step explanation:
Slant height of the square pyramid,
Just take one side(triangle)
The slant height tends to divide the base of the triangle in 2,
; we take one half of the triangle,
which now has a side with 6" and a base of 3"(since it was divided in two by the slant height)
;then apply the pythagoras theorem,
; (slant height)^2 = ( 6^2 - 3^2)
; slant height = square root of (36 - 9)
; slant height = square root of (27)
; which is... 5.2"
