A square based pyramid.
Depends on the tent. if it has a square bottom, and a triangular base. and triangular sides, then it would be a pyramid. A more general answer would be a polyhedron.
a triangular pyramid
A Pyramid
There are many possible answers but the most likely one, for your level, is a triangular prism.
# Square Pyramid # Rectangular Pyramid # Triangular Pyramid
A triangular pyramid is a pyramid with a triangular base; all pyramids are by definition three-dimensional figures, so a triangular pyramid is indeed 3D.

All pyramids are square based. It is a 3-dimensional solid object. It consists of four triangular faces, coming to a point, set on a square base ( 5th face). Any solid object that is NOT squared based is NOT a pyramid. e.g. A Tetrahedron. A triangular base, with three triangular faces.
The analogy for "square: triangle" is "cube: tetrahedron." Just as a square is a two-dimensional shape with four equal sides, a triangle is a three-dimensional shape with three vertices. Similarly, a cube is a three-dimensional shape with six equal square faces, while a tetrahedron is a three-dimensional shape with four triangular faces. Both pairs represent geometric shapes with increasing dimensions and different characteristics.
A pyramid with a square base, like the great pyramids of Egypt or Mexico. The bottom is square and they have four equal and identical triangular sides. This makes them different from a tetrahedron, a pyramid with a triangular base and three triangular sides.
Tetrahedron has three sides and a base all triangular.
