How does the shape of a cross-section of a 3D figure parallel to the base relate to the volume of the 3D figure?

The volume of  a 3D figure can be determined by the sum of  all the cross-sections of that 3D figure parallel to the base

Step-by-step explanation:

We need to understand what a cross-section of a 3D figure ?

A cross section is the shape we get when cutting straight through an object

and in geometry it is the shape made when a solid is cut through by a plane.

=> the cross section is parallel to the base of the figure.

So that the area of the cross-section is determined by its shape

Hence, The volume of  a 3D figure can be determined by the sum of  all the cross-sections of that 3D figure parallel to the base  

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
