Let's solve the problem based on the uploaded image.

Given Information:

• The figure is composed of cubic blocks.
• The steps form a rectangular prism structure divided into three levels.
• The base dimensions of the figure are $3 \times 3$, and the height is $6$ (split into 3 levels of height 2 each).

Step-by-Step Solution:

1. Determine the size of each cube:

   • Since the total height is $6$, divided into $3$ levels, the height of one cube is $2$.
   • Therefore, each cube is $2 \times 2 \times 2$ in dimensions.

2. Calculate the total number of cubes:

   • Level 1 (bottom level): This level is $3 \times 3$, so it contains $9$ cubes.
   • Level 2 (middle level): This level is $2 \times 2$, so it contains $4$ cubes.
   • Level 3 (top level): This level is $1 \times 1$, so it contains $1$ cube.
   • Total number of cubes = $9 + 4 + 1 = 14$.

3. Calculate the volume of each cube:

   • The volume of one cube = $2^3 = 8 \, \text{units}^3$.

4. Calculate the total volume:

   • Total volume = $14 \times 8 = 112 \, \text{units}^3$.

Final Answer:

Since $112$ is not one of the options, the correct answer is "none of these."

1. What is the formula for calculating the volume of a cube or rectangular prism?
2. How do we determine the dimensions of a single unit block from the overall structure?
3. Why is it important to carefully count the blocks at each level of the structure?
4. How would the volume change if the cubes were of size $1 \times 1 \times 1$?
5. How can we verify the calculations using an alternative method?

Tip:

When dealing with 3D structures, always break the figure into smaller, simpler components for easy calculations!
