Explanation:

Step1: Count unit - cubes for first shape

Count the number of unit - cubes in the first 'S' - shaped figure. By counting each individual cube, we find there are 22 unit - cubes.

Step2: Count unit - cubes for second shape

Count the number of unit - cubes in the second 'L' - shaped figure. There are 14 unit - cubes.

Step3: Count unit - cubes for third shape

The third figure is a cube - like structure. It has 3 layers with 9 unit - cubes in each layer. So the number of unit - cubes is \(3\times9 = 27\).

Answer:

First figure volume: 22 unit - cubes
Second figure volume: 14 unit - cubes
Third figure volume: 27 unit - cubes
