Answer:
2cm by 3cm by 3cm.
Explanation:
So, we are given the following data or parameters or information which is going to help us in solving this particular Question or problem;
=> We have a built rectangular prism.
=> The rectangular prism was built by using 18 cubes.
=> Each of the 18 cubes measure 1 cm on each side.
So, the dimensions of Carley's rectangular prism is given below as the multiples of 18 since each of the 18 cubes measure 1 cm on each side.
That's 2 cm × 3 cm × 3cm. Therefore, the length will be 2cm, breadth will be 3cm and height will be 3cm.
