Answer:
1:8
Explanation:
The original volume of the box can be calculated by multiplying the length, height, and width:
V = l x h x w = 40 x 8 x 20 = 6,400 cubic inches
If each of the dimensions is reduced by half, the new dimensions become:
Length = 20 inches
Height = 4 inches
Width = 10 inches
The volume of the new box can be calculated as follows:
V_new = l x h x w = 20 x 4 x 10 = 800 cubic inches
The ratio of the volume of the new box to the volume of the original box is:
V_new / V = 800 / 6,400 = 1/8
Therefore, the ratio of the volume of the new box to the volume of the original box is 1:8.
