Each cube in the figures below is one cubic unit.

Which figure does not have a volume of 48 cubic units? Select all that apply.

There are multiple figures given, so we need to calculate the volume of each and see which one is not equal to 48 cubic units.

Figure 1: There are 6 cubes in the length, 4 cubes in the width, and 2 cubes in the height. So, the volume is:

$6 \times 4 \times 2 = 48$

Therefore, Figure 1 has a volume of 48 cubic units.

Figure 2: There are 8 cubes in the length, 2 cubes in the width, and 3 cubes in the height. So, the volume is:

$8 \times 2 \times 3 = 48$

Therefore, Figure 2 also has a volume of 48 cubic units.

Figure 3: There are 3 cubes in the length, 4 cubes in the width, and 4 cubes in the height. So, the volume is:

$3 \times 4 \times 4 = 48$

Therefore, Figure 3 also has a volume of 48 cubic units.

Figure 4: There are 4 cubes in the length, 4 cubes in the width, and 3 cubes in the height. So, the volume is:

$4 \times 4 \times 3 = 48$

Therefore, Figure 4 also has a volume of 48 cubic units.

Since all four figures have a volume of 48 cubic units, none of them are the answer. Therefore, the question may be flawed or incomplete.
