Answer: 1852.5 cubic inches
Step-by-step explanation:
The Volume of cuboidal box is given by:-

Given: The length of box =
The width of the box =
The height of the box =
Now, the volume of box is given by:-

suppose 4:4:7 be 4x, 4x, 7x
or, 15x = 180°
or, X = 180/15
or, X = 12
therefore,
4x = 4x12= 48
4x= 4x12= 48
7x= 7x12= 84
so if you plus all of them you get 180
