Question

What lengths would allow you to calculate the volume of the oblique pyramid with a square base? Check all that apply.

AB and EF
AC, CB, and EF
AC and EF
AD, DB, and EF
AD, DC, and EF

Answer 1

All of them.

Reason: Volume = (1/3)(base area)(height). EF is the height. Any option that gives a side length or the diagonal of the square lets you get the base area (side = diagonal/√2, area = side^2). Each listed choice includes EF and at least one side or diagonal, so each lets you compute the volume.
