Final answer:
The volume of one baseball card case, with dimensions 12 cm by 6.5 cm by 1.25 cm, is 97.5 cubic centimeters.
Step-by-step explanation:
The volume of a rectangular object like a baseball card case can be calculated using the formula volume = length × width × height. In this case, we have a length of 12 cm, a width of 6.5 cm, and a height of 1.25 cm. We multiply these dimensions together to find the volume.
Volume of one case = 12 cm × 6.5 cm × 1.25 cm = 97.5 cm³.
Hence, the volume of one baseball card case is 97.5 cubic centimeters.
