Question

The above three figures have both the same height and same corresponding cross-sectional area. So, Figures will have the same volume.

• A. (X), (Y) and (Z)
• B. (Y) and (Z)
• C. (X) and (Y)
• D. (X) and (Z)

Answer 1

The correct option is A (X), (Y) and (Z)

Cavalieri’s principle states that two 3-dimensional solids of the
same height are equal in volume if the areas of their horizontal
cross-sections at every height “h” are equal.


So, all the three figures (X), (Y), and (Z) will have the same volume.
