Answer:
The options are not clearly written but, the volume of square based pyramid is 1/6 the volume of a cube because each of the six faces of the cube will contain one square based pyramid.
Step-by-step explanation:
Let the length of each side of your cube be x
the height of each of the six enclosed pyramids would be x/2. So the volume of each pyramid would be given by:
V = (1/3) × base area × height
V = (1/3) × x^2 × (x/2) = (x^3)/6
