Final answer:
The volume of the pyramid with a length of 2cm, width of 2cm, and height of 3cm is calculated using the formula V = (1/3) × length × width × height, which results in a volume of 4 cm³.
Step-by-step explanation:
To calculate the volume of a pyramid, the formula V = (1/3) × length × width × height is used. In this case, the given dimensions are length = 2cm, width = 2cm, and height = 3cm. Applying these dimensions to the formula gives:
V = (1/3) × 2cm × 2cm × 3cm
= (1/3) × 4cm² × 3cm
= 4cm³
Therefore, the correct choice is a) 4 cm³.
