Step-by-step explanation:
The height of the rectangular box whose volume is 27 cubic feet is 3 feet.
Let the height of the rectangualr box be h.
According to the given question.
The measures of the base of a rectangular box = 3 feet × 3 feet
Volume of the rectangular box = 27 cubic feet
As we know that, the volume of any rectangular box is calculated by taking its product of length, width and height.
So, the height of the rectangular box is given by
27 = 3 × 3 × h
⇒ 27 = 9 × h
⇒ 27/9 = h
⇒ h = 3 feet
Hence, the height of the rectangular box is 3 feet.
