What are the vertical and horizontal cross sections of a rectangular pyramid?
The vertical cross sections are trapezia or triangles. The horizontal cross sections are rectangles which are mathematically similar to the base.
What is a set of parallel cross-sections are congruent rectangles?
That's a statement that can apply to any rectangular prism.
Describe the cross-sections that are formed when a cylinder is intersected by a plane?
In Geometry, cross-section is the shape made when a solid is cut through by a plane. The cross section of a circular cylinder is a circle. * * * * * There are also cross-sections that are ellipses or rectangles.
How do you find the are of a cross?
You could consider the cross as two intersecting rectangles. Calculate the area of both rectangles and the area of the intersection (overlap). Then area of cross = sum of the areas of the rectangles minus the area of the overlap.
What is the difference between inscribed and circumscribed in integration?
When rectangles are inscribed, they lie entirely inside the area you're calculating. They never cross over the curve that bounds the area. Circumscribed rectangles cross over the curve and lie partially outside of the area. Circumscribed rectangles always yield a larger area than inscribed rectangles.

How can you work out the area of a cross?
Treat it as 3 rectangles.
Can you show me the cross sections of manufactured boards?
We need some pictues of the cross sections of manufactured boards. Thank you.
Why do we use an X in a railroad crossing instead of a cross?
It only looks like a letter X. In fact it is a cross.

What is the cross section of an octagonal prism?
Some cross sections are rectangle and octagon.
Why are cross-sections a useful tool for the geographer?
Cross sections are useful because it shows what the sightseers cant see, the landforms beneath the land surface.
What describes all cross sections of a square pyramid where the intersecting plane is parallel to the base?
All cross sections of a square pyramid that are parallel to the base are squares
