  • the length of a rectangular bin is 2 ft more than its width and the height is 3 ft less than its width . find the dimension of the bin if it's volume is 70 ft³.​

=====================================

CHECKING:

On the question have:

  • Length: x - 3
  • Width: x
  • Height: x + 2

Then,

  • x · (x - 3)(x + 2) = 70ft³

Hence,

  • Length: 3ft
  • Width: 5ft
  • Height: 7ft
