In Apple Numbers I want a cell to have 4x8x7 (or 4*8*7) to show the detail of the volume, and in another cell I want that volume calculated 4*8*7=224 based on the first cell. But it doesn't consider the first cell as an operation. Which formula can help ?
You could use the string concatenation operator '&' and make a formula like this:
=B2&" X "&B3&" X "&B4 which would display "4 X 8 X 7"
then have another formula that actually calculates the function:
=B2*B3*B4 which would display "224"
