One-third
y cm 3
Step-by-step explanation:
We will be assuming we are dealing with a square based pyramid, which has the shape of its base as a square. The volume of a pyramid is got by multiplying its base area, height and a factor - 1/3.
For our square based pyramid, we will assume it has dimensions; length breadth and height to be (x , x, and y) respectively.
(the length and breadth are the same because it has a square base)
hence the volume will be
This will be
Hence our correct answer is option B: One-third
y cm3
