The volume of a pyramid is given by
  V = (1/3)Bh
where B is the area of the base and h is the height (12 units).

The base is a right triangle, with sides 6 and 8, so its area will be
  B = (1/2)(6 units)(8 units) = 24 units²

Putting the numbers into the volume formula, we have
  V = (1/3)(24 units²)(12 units)
  V = 96 units³

The appropriate choice is ...
  B)   96 units³
