3 in.
more cubes are added to the prism.
The volume of the new rectangular prism is

Additional cubes added to the rectangular prism= 72cubes

Volume of new rectangular prism = 108in³

Step-by-step explanation:

The question is incomplete without the diagram and not clear to understand.

Let's determine how to find answers to the above using the following:

The diagram used for solving the question has been attached.

From the diagram, the base of the rectangular prism has length =6inches and width = 6inches

Height = 1inch

If 2more layers are added, then height becomes 3inches sinch the two additional layer has same dimensions as the base.

The bottom layer has 6 by 6 dimension

Area = 6×6 = 36in²

Since 1 cube = 1 inch

Number of cubes in the base = 36cubes

Since two layers were added, Additional cubes added to the rectangular prism = 2×36 = 72cubes

Volume of rectangular prism = length×breadth×height

= l×b×h

dimension of new rectangular prism

Length = 6in

Breadth = 6in

Height = 3in

Volume of new rectangular prism = 6×6×3

Volume = 108in³

the answer is here: : )
