Given that volume of a pyramid that fits exactly inside a cube is 9 cubic feet
We are to find the volume of a cube.
Since the pyramid fits exactly in the cube so its base will be a square with length and height equal to "x"
height = x
area of base square =
[ since area of square = ]
The volume of cube is given as:
Where "x" is the length of side
Thus volume of cube is 27 cubic feet
