The frustum of a cone or a pyramid is the 3D shape that is left-over after you cut the top off (see the pictures below for examples). The slice the you make when cutting the top off will always be parallel to the base of the shape.
3 A frustum is cut from a square based pyramid as shown below. The height of the frustum is 7m The height of the pyramid on top of the frustum is 8.75m The large square base is 9mwide. The square top is 5mwide. Calculate the volume of the frustum. Give your answer to 2decimal places.

A frustum is a 3D shape enclosed between the two parallel planes of another solid that is cut into two parts. There are generally two types of frustum: A cone frustum: Created by cutting the cone from the vertex or apex. A plane parallel to the base of the cone cuts the top of the cone or the apex to create a frustum.

2024年3月15日 · A frustum is a solid that has been cut off from an object by a plane parallel to the base. Here is an example of a frustum of a square-based pyramid, the first example we’ll be looking at below: We’ve cut the pyramid ABCDE with a horizontal plane, resulting in the square FGHI parallel to ABCD.
Question 1: Shown is a square based pyramid A. (a) Find the volume of the square based pyramid. Shown is a smaller square based pyramid B. (b) Find the volume of the smaller square based pyramid. A frustum is created by removing the Pyramid B from the top of Pyramid A. (c) Find the volume of the frustum.
