From the given image, the problem appears to involve calculating the number of cubes needed to fill a cuboid when it is completely stacked. The provided information mentions 6 cubes along the height, and we can assume the width and depth dimensions need to be factored in as well.

Solution Steps:

1. Understand the Problem:

   • A cuboid is fully filled with cubes.
   • The number of cubes along the height is given as 6.

2. Formula to Calculate Total Cubes: The total number of cubes required to fill a cuboid is the product of the number of cubes along its: $\text{Total cubes} = (\text{Cubes along height}) \times (\text{Cubes along length}) \times (\text{Cubes along width})$

3. Extract Dimensions: From the diagram, if the other two dimensions (length and width) are evident, we can use the formula to compute the total number of cubes.

Please confirm or provide any additional information on the length and width dimensions of the cuboid (or let me extract them further from the image if available). Let me know if you'd like clarification or details!
