The surface area of the pyramid is 18,541 mm² . Option C
<h3>How to determine the surface area</h3>
The formula for surface area of a regular hexagonal prism is expressed as;
Where;
- a is the edge length = 44 millimeters
- h is the height = 95 millimeters
A = 2. 598 ( 44)² + 3(44)
Simplify
A = 5029. 728 + 132
Find the square root
A = 5029. 728 + 132(102. 357)
expand the bracket
A = 5029. 728 + 13511. 124
A = 18, 540. 85
A = 18,541 mm² in thee nearest square millimeter
Thus, the surface area of the pyramid is 18,541 mm² . Option C
