The first layer of a rectangle prism is packed with 25 unit cubes. There are no spaces or gaps between the cubes. The prism is 7 unit cubes tall. Which expression represents the volume of the rectangular prism?

So, the answer is 175 but in an expression it is 25x where x would be the height in this situation it is 7.

Step-by-step explanation:

So basicly if there is 25 units and there are 7 layers of that 25 units you would multiply 7 by 25 to get 175.

Hence, in an expression it would be 25x where x would be 7
