Question

A slice is made parallel to the base of a square pyramid.

a) What is the shape of the resulting two-dimensional cross-section?

A slice is made perpendicular to the base of a right rectangular pyramid through the vertex.
b) What is the shape of the resulting two-dimensional cross-section?
c) What is the area of the resulting two-dimensional cross section?

Answer 1

a) Triangle.

b) Triangle.

c) The area is 110 cm.

Explanation:

The shape is given because it is a cross section of a Pyramid which we can see shaded in grey.

The area is given by the base times hight devided by 2. So 10cm * 22cm/2= 110cm.

Hope this helped ;)
