Leah fills the rectangular prism with cubes that have side lengths of 1/3inch.How many cubes does she need to fill the rectangular prism?

depends on the size of the prism.

Wooooow....... Great help!!!

To find out how many cubes Leah needs to fill the rectangular prism, we need to calculate the volume of the rectangular prism and then divide it by the volume of a single cube.

Step 1: Find the volume of the rectangular prism.
The volume of a rectangular prism can be calculated by multiplying its length, width, and height.
Let's assume the length of the rectangular prism is L inches, the width is W inches, and the height is H inches.
So, the volume of the rectangular prism is V = L × W × H cubic inches.

Step 2: Find the volume of a single cube.
The volume of a cube can be calculated by multiplying the length of one side by itself three times.
In this case, the side length of the cube is 1/3 inch.
So, the volume of a single cube is VC = (1/3) × (1/3) × (1/3) cubic inches.

Step 3: Divide the volume of the rectangular prism by the volume of a single cube.
V divided by VC will give us the number of cubes Leah needs to fill the rectangular prism.

In conclusion, the number of cubes Leah needs to fill the rectangular prism is V divided by VC.
