Pls help me fill in the blank to the question

The blanks are filled as follows;

1 - 2, 2 - count, 3 - 12, 4 - 13, 5 - 3, 6 - 15, 7 - 15, 8 - 15, 9 - 15 cubic inches.

Step-by-step explanation:

Step 1:

First, we separate the entire figure into two rectangular prisms. So two fills the first blank.

Next, we count the number of inch cubes one each prism so count fills the second blank.

For the prism on the left, there are 3 up and 4 across so there are 12 inch cubes. So 12 fills in the third blank.

For the prism on the right, we start counting after 12. So 13 fills in the fourth blank.

We count 3 inch cubes on the right prism in all. So 3 inch cubes fills in the fifth blank.

Step 2:

So there are 12 + 3 = 15 inch cubes in the figure so 15 fills in the sixth blank.

As each inch cube represents 1 cubic inch. 15 inch cubes = 15 cubic inches. So 15 is the answer to the seventh and eighth blank.

The volume of the solid figure is 15 cubic inches which fills in the ninth and final blank.
