What is the volume in cubic ft of a box that is 3 ft long 8 ft wide and 16 ft high?

Answer 1

If, as here, the space is rectilinear -- that is, it comprises straight lines and right angles -- then all you have to do is multiply the three dimensions. In this case, 3 x 8 x 16 = 384. If the box is oddly shaped, sometimes you can solve it by dividing it into solvable pieces. In fact, that's what calculus is all about -- dividing the space into many solvable pieces.
