Final answer:
The volume of the cell with given dimensions is calculated as 40 m × 40 m × 40 m, which equals 64,000 m³. This is option 1).
Step-by-step explanation:
The volume of a cell with dimensions of length 40 m, width 40 m, and height 40 m can be calculated using the formula for the volume of a rectangular prism or cube, which is length × width × height. So, the volume of the cell is:
40 m × 40 m × 40 m = 64,000 m³.
This means that the correct answer to the question is 64,000 m³, which corresponds to option 1). The other options incorrectly convert this volume to kilometers cubed or incorrectly format the units.
