A cuboid.
octagon
A cube is a three-dimensional geometric shape with six equal square faces, twelve edges, and eight vertices. All its angles are right angles, and its faces meet at 90-degree angles. This symmetrical shape has equal dimensions in length, width, and height, making it a perfect example of a regular polyhedron.
6 faces with 4 right angles on each face, so 6 x 4 = 24 right angles
A rectangular prism has six faces; each face has four right angles. There are 24 right angles in all.
Three shapes that have faces with perpendicular edges are the cube, rectangular prism, and the right rectangular prism. In these shapes, the faces intersect at right angles, creating edges that are perpendicular to one another. This characteristic is a defining feature of their geometric structure, allowing for the formation of right angles throughout the shape.
A tetrahedron.
A cuboid has twenty four right angles. A cuboid is a shape with six faces that are either squares or rectangles. Each face has four right angles.
A cube has 6 faces, each having 4 right angles, for a total of 24 angles.
octagon
The solid is a cuboid, or "right rectangular prism" in which all angles are right angles. It is a box shape, or regular hexahedron.
If the question is about a plane shape with exactly 3 right angles it could be an irregular polygon of 5 or more sides. If the shape can have more than 3 right angles then a square or rectangle are also possible. Finally, in 3 or more dimensions, a polyhedron with any number of faces can have 3 or more right angles.
A 3-dimensional shape with three pairs of rectangular faces opposite one another; meeting at right angles.
Square-based pyramid.
