#1 Find the surface area of the regular triangular pyramid. The surface area is units. (Round your answer to the nearest hundredth.)

Surface area of a regular triangular pyramid can be calculated by

Surface area = Area of 3 triangular surface + Area of base triangle

= (3 * Area of surface triangle) + ( Area of the base triangle (equilateral triangle with side length 8))

= (3 * ( (1/2) * base * height ) + ( (?3)* base * base / 4)

= 216 + 27.712

= 243.712 sq units
