(a)
To draw: The pyramid-shaped top of the W monument.
(a)

Answer to Problem 17IP
The pyramid-shaped top is shown below.
Explanation of Solution
Given information:
Consider the given shape of the W monument.
Calculation:
In the shape, the top of the shape has a square pyramid with square base and four triangular faces. Draw the shape of pyramid.
Conclusion:
Therefore, the pyramid-shaped top is shown above.
(b)
To identify: The base, faces and edges of the pyramid shaped top.
(b)

Answer to Problem 17IP
The base, faces and edges of the pyramid shaped top is shown below.
Explanation of Solution
Given information:
Consider the pyramid-shaped top of the W monument.
Calculation:
Label the base, faces and edges of the shape.
Conclusion:
Therefore, the base, faces and edges of the pyramid shaped top is shown above.
(c)
To find: The shape formed from the pyramid-shaped top when it is cross-sectioned from vertical, angled and horizontal.
(c)

Answer to Problem 17IP
Triangle, trapezoid, and square are formed from the cross-sectioned from vertical, angled and horizontal, respectively.
Explanation of Solution
Given information:
Consider the pyramid-shaped top.
Calculation:
When the pyramid shape is cut vertically, a triangle is formed.
When the pyramid shape is cut horizontally, a square is formed.
When the pyramid shape is cut through an angle, a trapezoid is formed.
Conclusion:
Therefore, triangle, trapezoid, and square are formed from the cross-sectioned from vertical, angled and horizontal, respectively.
(d)
To find: The shape formed from the W monument when its top and bottom cut through an angle.
(d)

Answer to Problem 17IP
Trapezoid and quadrilateral is formed when the W monument when it’s top and bottom cut through an angle, respectively.
Explanation of Solution
Given information:
Consider the given shape of the W monument.
Calculation:
Since the top of the monument has a pyramid shaped and the bottom has a rectangular prism.
When the pyramid shape is cut through an angle, a trapezoid is formed.
When the rectangular prism shape is cut through an angle, a quadrilateral is formed.
Conclusion:
Therefore, trapezoid and quadrilateral is formed when the W monument when its top and bottom cut through an angle, respectively.
