Respuesta :

The combined volume is 320 cu. in.

The volume of the bottom of the box is given by the formula

V = lwh.  For this box, we have

V = 8(8)(4) = 256 cu. in.

The volume of the top of the box is given by the formula

V = 1/3lwh.  For this box, we have

V = 1/3(8)(8)(3) = 64 cu. in.

Together, this makes 256+64 = 320 cu. in.
