The inner orbit is designated by the number

224 in.^3

Step-by-step explanation:

The volume of a prism is the area of the base (A) multiplied by the height of the prism (h).

volume = Ah

The base is a triangle, so its area is bh/2,

where b = base of the triangle, h = height of the triangle

The area of the base is

bh/2 = (4 in. * 7 in.)/2 = 14 in.^2

The volume is:

volume = Ah = 14 in.^2 * 16 in. = 224 in.^3
