CUBE AND CUBOID:- Faces,vertex, diagonals,edges,Lsa,Tsa And volume

Cuboid: A cuboid is a three-dimensional figure formed by six rectangular surfaces, Each rectangular surface is a face. Each solid line segment is edge, and each point at which the edges meet is vertex. A rectangular solid has six faces, twelve edges, and eight vertices. Edges mean sides and vertices mean corners. Opposite faces are parallel rectangles that have same dimensions.
The surface area of a rectangular solid is equal to the sum of the areas of all the faces.
Total surface area = 2(lb + bh + hl )
Curved surface area = 2h(l + b)
