Question 954336
b=base edge=4m; s=slant height=8m
lateral surface area=(6)(1/2)bs=3bs=3(4m)(8m)=96 sq m
ANSWER 1: The lateral surface area is 96 square meters.
Area of base:
{{{Area=((3sqrt(3))/2)b^2}}}={{{2.598(4^2m^2)=2.598(16m^2)}}}=41.57m
The area of the base is 41.57 square meters. 
Surface area=lateral area + base area=96 sq m+41.57 sq m=137.57 sq m
ANSWER 2: The surface area is 137.57 square meters.
