octagon
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 shape with five sides would be a pentagon, but a shape can not have 5 right angles. Squares and Rectangles are both shapes with 4 sides and 4 right angles. They are the only shape with the same amount of right angles as there is sides.
A regular 5 sided pentagon is one such example of a shape having no right angles
A tetrahedron.
A cube has 6 faces, each having 4 right angles, for a total of 24 angles.
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.
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 sphere!
A cuboid is a three-dimensional shape with six rectangular faces, eight vertices, and twelve edges. It has opposite faces that are equal in size and shape, and all angles are right angles. The volume of a cuboid is calculated by multiplying the length, width, and height together.
6 faces with 4 right angles on each face, so 6 x 4 = 24 right angles
