How many faces does this shape
have? How many of its faces look like
this rectangle? How many faces are squares? And how many faces are circles?
We’re shown a model of a 3D
shape. Do you know the name of this
shape? It’s a cuboid or a rectangular
prism. We can imagine that this cuboid is
a cardboard box. And if we were to flatten the box,
it would look like this. Thinking of the 3D shape in this
way helps us to count its faces. How many of the faces are
rectangles? There’s one, two, three, four
rectangular faces.
How many of the faces are
squares? There are two. How many of the faces are
circles? The shape doesn’t have any circular
faces. If four of its faces are rectangles
and two are squares, the cuboid has six faces. Four plus two is six. The cuboid has six faces; four are
rectangles, two are squares, and none are circles.
