Answer 1

Inner length = (x - a) units,  Inner breadth = (y - a) units, Inner height = (z - a) units

Step-by-step explanation:

Here, we can understand that the thickness 'a' is uniform.

The outer dimensions are given as:

• Length = x units

• Breadth = y units

• Height = z units

These, dimensions include the thickness. If we subtract the thickness from these dimensions, we get the corresponding inner dimensions.

It means.

Inner dimensions:

• Inner length = (outer length - a)

                             = (x - a) units

• Inner breadth = (outer breadth - a)

                               = (y - a) units

• Inner height = (outer height - a)

                            = (z - a) units
