Write down the number of faces of each of the following figures:
A. Cuboid
B. Cube
C. Triangular prism
D. Square pyramid
E. Tetrahedron
A. 6
Face is also known as sides. A Cuboid has six faces.
The six faces of the cuboid are: 1) ABFE 2) BFGC 3) GHDC 4) HEAD 5) DCBA 6) HGFE |
Book, Matchbox, Brick etc. are examples of Cuboid.
B.6
A Cube has six faces and all faces are equal in length.
The six faces of the cube are: 1) ABFE 2) BCGF 3) CDHG 4) ADHE 5) GHFE 6) ABCD |
Sugar Cubes, Dice etc. are examples of Cube.
C. 5
A Triangular prism has two triangular faces and three rectangular faces.
The five faces of the triangular prism are: 1) ABE 2) ABCD 3) BCFE 4) AEFD 5) FDC |
D. 5
A Square pyramid has one square face as a base and four triangular faces as the sides. So, Square pyramid has total five faces.
The five faces of the square pyramid are: 1) ABC 2) ACD 3) ABE 4) AED 5) BEDC |
E. 4
A Tetrahedron (Triangular Pyramid) has one triangular face as a base and three triangular faces as the sides. So, Tetrahedron has total four faces.
The five faces of the tetrahedron are: 1) ABC 2) ACD 3) ABE 4) AED 5) BEDC |
