We are given a diagram.
We need to find the number of cubes would we use to make the given structure.
In order to find the number of cubes, we need to find the length, width and height of the given structure.
For the given structure, length = 4 units.
Width = 3 units and
Height = 2 units.
Length × width × Height = 4 × 3 × 2 = 24 cubes.
Now, subtracting missing number of cubes.
Missing number of cubes = 2+5 = 7.
Reamining number of cubes =24 -7 = 17 cubes.
<h3>Therefore, correct answer is 17 cubes.</h3>
