A pyramid is a four-sided, three-dimensional figure.
Three-dimensional. It has height, width and depth.
A three dimensional shape is where you have height, width, and length where as in a two dimensional shape you only have height and length
triangle
the shape was in three-dimensional or 3-D
An eight-sided three-dimensional shape is called an octohedron.
12-sided two dimensional shape: dodecagon12-sided three dimensional shape: dodecahedron
A two-dimension shape with eight sides is an octagon. A three-dimensional object with eight sides is an octahedron.
A hexahedron is a three-dimensional geometric shape having six sides; a hexagon is a two-dimensional six-sided shape.
Eight sided three-dimensional shape. Often this looks like two pyramids stuck together at their bases.
A cube or a hexahedron
It is a hendecahedron.
An octahedron is an eight-sided polyhedron (which is a three-dimensional polygon).
The shape is an octagon.
if it is a 2 dimensional shape you do height multiplied by width but if it is a three dimensional figure you multiply length by width by height and there are three dimensions.
A pyramid is a four-sided, three-dimensional figure.
This question is faulty. Only 2-dimensional shapes can have their sides counted. For a 3-dimensional shape, you must count either edges or faces.
