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.
A right prism is a three-dimensional geometric shape with two parallel, congruent bases connected by rectangular lateral faces. The sides of the lateral faces are perpendicular to the bases, which means the angles between the base and the lateral faces are right angles. Right prisms can have bases of any polygonal shape, resulting in various types, such as a right triangular prism or a right rectangular prism. The volume of a right prism can be calculated by multiplying the area of the base by the height of the prism.
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.
there are 24 right angles in all faces of a cube
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.
A sphere!
A cuboid has 6 faces, each of which is a rectangle. A rectangle has 4 right angles. Therefore, each face of the cuboid has 4 right angles. To find the total number of right angles in all the faces of the cuboid, you would multiply the number of right angles per face (4) by the number of faces (6), resulting in a total of 24 right angles in all the faces of a cuboid.
