1. 324 cm3
2. 108 cm3
3. 36 cm3
4. 152 cm3

The correct answer is 108 cm3.

The formula for the volume of a square pyramid is:

V = (1/3) * base area * height

Since the base is a square with a length of 9 cm, the base area is:

base area = 9 cm * 9 cm = 81 cm2

Plugging in the given values:

V = (1/3) * 81 cm2 * 4 cm = 108 cm3

To find the volume of a square pyramid, you can use the formula: V = (1/3) × (base area) × height.

1. First, find the base area. Since the base is square, you can use the formula for the area of a square: base area = length × width. In this case, the length of the base is 9 cm, so the base area = 9 cm × 9 cm = 81 cm².

2. Next, substitute the values into the formula for volume. V = (1/3) × (81 cm²) × 4 cm.

V = (1/3) × 324 cm³.

3. Multiply 1/3 by 324: V = 108 cm³.

Therefore, the correct answer is option 2: 108 cm³.
