Respuesta :

384/6 (amount of faces) = 64
64/2 (area= l*w) = 32
32*3 (volume=l*w*h) = 96

I'm pretty sure this is correct, maybe just double check and see if this makes any sense according to what you're learning? I'm almost 100% sure. Hope this helps!
the volume of the cube would be 
V=512 in cubed
