I think you mean pyramids so
surface area
there are triangles on the faces of the pyramids so 1/2BH=SA of 1 of the side so for the whole side
surface are of each side=BH
B=5
H=8
(5)(8)(1/2)=20
4 sides
(4)(20)=80= top surface area
the surface are of the base
(5)(5) =25
25+80=105 sq units
I can't see 6 or 7 so I'm done

The area of the shaded region is Area of the Circle - Area of the Triangle + Area of the Square.
Hence, option D) is the correct answer.
<h3>What is the representation of the area of the shaded region?</h3>
From the diagram below;
- A triangle is inscribed in a circle
- A Square is inscribe in a triangle.
- Only the the circle and square are shaded.
To get the shaded region, we say;
Area of the Circle - Area of the Triangle + Area of the Square.
The area of the shaded region is Area of the Circle - Area of the Triangle + Area of the Square.
Hence, option D) is the correct answer.
