MCQ

A rectangular parallelopiped is formed by planes drawn through the point $(5, 7, 9)$ and $(2, 3, 7)$ parallel to the coordinate planes. The length of an edge of this rectangular parallelopiped is:

A
$2$
B
$3$
C
$4$
✓
all of these

✓

Answer

Correct option: D.

all of these

The give point $(5, 7, 9)$ and $(2, 3, 7)$ are two diagonally opposite vertices of the parallelopiped as all of theire coordinates.
Edges of the paralleloppiped $= |5 - 2|, |7 - 3|, |9 - 7|$
$=3, 4, 2.$
