Final answer:
The volume of a rectangular prism is calculated by multiplying its dimensions: length, width, and height. For the given prism with dimensions 8 cm × 5 cm × 3 cm, the volume is 120 cm³. The correct answer is (A) 120 cm³.
Step-by-step explanation:
To find the volume of a rectangular prism, you multiply its length by its width by its height. The formula to calculate volume is V = l × w × h. Given the measurements of the large rectangular prism are 8 cm, 5 cm, and 3 cm, the volume can be calculated as follows:
V = 8 cm × 5 cm × 3 cm = 120 cm³.
Therefore, the correct answer is (A) 120 cm³.
