24 right angles

Yes

The lateral faces will be parallelograms, and the opposite faces will be congruent. In a right prism, the lateral faces will be rectangles.

A rectangular prism is a hexahedron with six rectangular faces, each on which meets two others at right angles. In the special case that the rectangles are squares the shape is a cube so a cube is a special case of a rectangular prism.

rectangular prism all angles are acute angles yes or no? * * * * * No, none of the angles are acute. They are all right angles because each face is a rectangle and each angle in a rectangle is a right angle.

There are normally three rectangular faces and so their angles are all right angles. But there are no restrictions on the angles of the triangular faces other than that they sum to 180 degrees.

24 right angles

The solid is a cuboid, or "right rectangular prism" in which all angles are right angles. It is a box shape, or regular hexahedron.

A triangular prism has three rectangular faces which, between them, will have 4*3 = 12 right angles. It also has two triangular faces and these can have another 2 right angles. So the answer is 12 or 14, depending on whether the triangles are right angled or not.

Yes

They're 3D figures. Also, a cube is a type of rectangular prism (This can be taken from the fact that a square is a type of rectangle, because a rectangle is a parallelogram with right angles). Both figures have 6 faces, 8 vertices, and 12 edges. All the angles are right angles (in measure of 2-dimensional views). Note: Even though a cube is a type of rectangular prism, not all rectangular prisms are cubes.

A triangular block prism has four right angles on each of the three faces, so the total 'on all the faces' = 12.

rectangular prism all angles are acute angles yes or no? * * * * * No, none of the angles are acute. They are all right angles because each face is a rectangle and each angle in a rectangle is a right angle.

They are both hexahedra with three pairs of parallel faces meeting, three at a time, at right angles. All edges (sides) of a cube are of equal length whereas in a rectangular prism they are not.
