Which expression represents the height of the pyramid?
Answer
A
the fraction with numerator 3 cap v and denominator y squared units
B
open paren 3 cap v minus y squared close paren times units
C
the fraction with numerator cap v and denominator 3 y squared units
D
open paren cap v minus 3 y squared close paren times units
Explanation
The volume of a pyramid is V = (1/3) × base area × height. With a square base of side y, the base area is y², so V = y²h/3. Solving for h gives h = 3V/y², which is choice B.
