Peter makes two slices through a three-dimensional object. One plane is
parallel to the base; the cross-section is a square. The other plane is
perpendicular to the base; the cross-section is a rectangle. What three-
dimensional shape did Peter cut?

SPHERE

if you cut a sphere paralell to it's base, you get a circle

if you cut it perpendicular, you get  a circle

circle=circle so this works

CUBE

if you cut a cube paralell to it's base, you get a square

if you cut it perpendicular, you get  a square

square=square so this works

the answer is d. (1.2, -4.7) on edgn

hope this !
