Answer:

16 inches

Step-by-step explanation:

The sum of the volume of all the cubic blocks should equal the volume of the rectangular prism.

Volume of 64 1-inch cubic blocks = 1 * 64 = 64

And, we know volume of rectangular prism is length * width * height

So, we can write:

64 = length * 2 * 2

64 = length * 4

length = 64/4=16

Thus, the rectangular prism is 16 inches long
