To calculate the volume of the rectangular prism in the image, we need to count the total number of cubes within it.

Step-by-step process:

1. Count the dimensions:

   • The rectangular prism appears to have a structure of $3 \times 3 \times 4$, meaning:
     • Length: 3 units
     • Width: 3 units
     • Height: 4 units

2. Calculate the volume:

   • The volume $V$ of a rectangular prism is given by the formula: $V = \text{Length} \times \text{Width} \times \text{Height}$
   • Using the dimensions: $V = 3 \times 3 \times 4 = 36 \text{ cubic units}$

Thus, the volume of the rectangular prism is 36 cubic units.

Tip:

When counting cubes in a 3D shape, visualizing layers or rows can help avoid miscounting, especially in complex structures.
