hey guys what are you doing we're down
in the valley just get on the sphere
what's a sphere hey guys we're here
watching 3d shapes go by check it out
this here's a cube it has six sides it's
like a box or a block okay that cube is
messed up
that's called a cuboid it's like a
stretch cube tell me and here we have a
pyramid it has a square base and four
triangles his sides pyramids can have
different shaped bases a pyramid that's
a silly way it's not a silly word you
just haven't heard of it before
I'm sorry pyramid that's called a cone a
hollow cone can hold ice cream yay this
is known as a cylinder it has a circular
or oval base and straight sides or a cam
a rolling pin and pipes are cylinders
that are hollow in the middle cylinders
are everywhere Wow this here is a sphere
it looks like a ball or that round thing
I stepped on bubbles all raindrops can
also be spheres
a half a sphere is called a hemisphere
someone took a triangle and gave it a
stretch that's known as a prism it's
spelled P R I SM prism prisms can have
different sides as well it's kind of
like a spring this is known as a helix
it's a curve that wraps around the shape
of a cylinder it's like a spiral
staircase or a strand of DNA the one
with 12 sides is a dodecahedron the one
with 20 sides is an icosahedron maybe we
can talk about those on another day of
course there are all kinds of tricky
shapes we'll talk about those later hey
guys what are you doing well I happened
upon this 3d shape I'm gonna take your
home and eat it
nom nom t-rex don't eat that that's a
torus what did you call it torus
I do not know what you're talking about
[Laughter]
