Answer 2

Cube method:

Since the rectangular prism is made up of 4 cubes, we can simply calculate the volume of one cube and multiply it by 4 to get the volume of the rectangular prism.

Volume of one cube = 1^3 = 1 cubic inch

Volume of rectangular prism = 4 x 1 cubic inch = 4 cubic inches

Therefore, the volume of the right rectangular prism is 4 cubic inches.

Formula method:

The formula for finding the volume of a rectangular prism is:

Volume = length x width x height

In this case, we know that the length, width and height are all equal to 1 inch (since each cube is 1 inch on each side).

Therefore, the volume of the rectangular prism is:

Volume = 1 inch x 1 inch x 1 inch = 1 cubic inch

Since there are 4 cubes, we need to multiply 1 cubic inch by 4 to get the total volume:

4 x 1 cubic inch = 4 cubic inches

Therefore, the volume of the right rectangular prism is 4 cubic inches.
