How big is 1.9 cubic feet of space?

Answer 1

If the question is seeking the dimensions of a volume of 9 cubic feet the answer is that there are infinitely many solutions.

Take any two positive numbers x, and y and consider a cuboid with sides of x feet, y feet and 9/(x*y) feet. The volume of such a cuboid will be x*y*9/(x*y) = 9 cubic feet. Since there are infinitely many possible values for x and infinitely many values for y, there are infinitely many cuboids with a volume of 9 cubic feet.

And that is assuming the volume is in the shape of a cuboid. It could be a sphere, an ellipsoid, prism, pyramid, or any one of a host of regular and irregular solid shapes.

Answer 2

1 foot = 30.48 cm = 12 inch

Answer 1 = 0.9 cubic feet = 0.9 x (30.48)3 cubic cm = 25485.162 cubic cm

Answer 2 = 0.9 x 123 cubic inch = 1555.2 cubic inch

Answer 3

1.9 cu ft = 53.8 litres.

Answer 4

2 ft
