- A rectangular pyramid is the pyramid with a triangular face on all sides having a top pick and a rectangular base.
- Trapezoidal prism is the extension of the quadrilateral which has only one pair. When you cut the pyramid from the top with a cross-section it is called a trapezoidal prism.
In the given figure the base of a rectangular pyramid has 2cm width and 4cm length. This pyramid has been cut by a section of a 2-dimensional cross-section having the length of 2 cm and the width of 1 cm.
To find out the area of the sectional part the cross-sectional part should be formulated,
Area of the cross section = Length X width
[tex]A= l\times b[/tex]
[tex]A= 1\times 2[/tex]
[tex]A=2[/tex]
Hence, the area of the cross-sectional part is 2 cm square.
