Answer:
Part a) Rectangle
Part b) Triangle
Step-by-step explanation:
Part A) A cross section of the rectangular pyramid is cut with a plane parallel to the base. What is the name of the shape created by the cross section?
we know that
When a geometric plane slices any right pyramid so that the cut is parallel to the plane of the base, the cross section will have the same shape (but not the same size) as the base, So, in the case of a right rectangular pyramid, the cross section is a rectangle
Part b) If a cross section of the rectangular pyramid is cut perpendicular to the base, passing through the top vertex, what would be the shape of the resulting cross section?
we know that
Cross sections perpendicular to the base and through the vertex will be triangles
Answer:24-25a
Step-by-step explanation:
The volume of the triangle will be V=1.6875 cm^3
It would be (B) because 450+200x4=2620 fence posts
Answer:
25
Step-by-step explanation:
4x = 100
x = 100/4
x = 25
