let each side of the cube be x
volume of cube = x^3
area of one face = x^2
4 times the area of all its faces = 4(6x^2) = 24x^2
x^3 = 24x^2
x^3 - 24x^2 = 0
x^2(x-24) = 0
x = 0 , not acceptable
or
x = 24
Volume = 24^3 units^3 = ....
distance dropped = 16t^2
when t = 2, distance dropped = 16(4) = ....
