2*area of triangular faces + perimeter of triangle*length of prism (not prisim).
okay, to find the base of a triangular prism you just b = 2a/h (base = 2 * area/height)
To find the surface area of an prism you must do the following: EXAMPLE: S.A.( SURFACE AREA) and L.A.(LATERAL AREA) S.A.=L.A. +2B S.A.=113 +2 (28) S.A.= 113 + 56 S.A.=169 IN.2( THE 2 MEANS SQUARE ROOT)
use the net to find the lateral area of the prism 3m 6m 3m 6m 15m
L=PH L=PH Lateral Area= (Perimeter of the base)(the height of the figure)
