Hello!
First you have to find the volume of the cube
To do this we use the equation a^3
a is a side length
24^3 = 13824
The maximum pyramid can have a maximum side length of 24 and a maximum height of 24 since that is what the cube measurements are
The equation for the volume of a square pyramid is

a is side length
h is height
put in 24 for the values

Square the 24

Divide
576 * 8 = 4608
The answer is B) 4608 cubic centimeters
Hope this helps!
