What is the maximum volume of a square pyramid that can fit inside a cube with edges 18 cm long?A. 5832 cm3B. 2916 cm3C. 1944 cm3D. 972 cm3

we know that
[volume of a square pyramid]=(1/3)*b²*h
b--------> is the length side of the cube-------> 18 cm
h-----> is the height of the cube-------> 18 cm

[volume of a square pyramid]=(1/3)*18²*18----> 1944 cm³

the answer is
1944 cm³
