what do u think?

anonymous · Answer

I think maybe just the rectangle?? @sdfgsdfgs

sdfgsdfgs · Answer

pyramid is correct as the cross sections will not be identical. but how about other shapes?

anonymous · Answer

triangular prism too ? because the sphere doesn't really have a base, and the cone has a point at the top so. @sdfgsdfgs

triciaal · Answer

we are only looking at the cross-section so I think only the rectangular pyramid

sdfgsdfgs · Answer

prism is correct too. for cone, the cross sections are all circle BUT are they same size? remember they must be identical...

anonymous · Answer

so is it not just the prism and pyramid? there's something else too? @triciaal @sdfgsdfgs
