A rectangular prism has six faces; each face has four right angles. There are 24 right angles in all.
acute on all of them
The rectangular prism is the 3D analogue of a rectangle. The main similarity is that all sides meet at right angles.
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.

I presume you mean a rectangular prism. Assuming all the angles are right angles, so that it is a rectangular parallelepiped, the volume is just the product of the three dimensions. I get 90.
You are describing a rectangular prism or a cube,
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).

Note: Even though a cube is a type of rectangular prism, not all rectangular prisms are cubes.
a Rectangular Prisim
If the prism is a rectangular parallelepiped (that is, all the angles are right angles), just add the squares of the 3 dimensions (length, width, and height) together, and take the square root. This involves 2 applications of the Pythagorean Theorem.
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.
acute angles are angles that are smaller than 90 degrees. all acute angles are all angles that are less than 90degrees
This depends on whether or not the prism is a rectangular prism or not. Simple shape prisms (rectangular, triangle, octagonal, hexagonal) all have rectangular faces.
