Answer 2

1. Answer: (a) 8

Explanation: A cube has 6 faces, 8 Vertices, and 12 Edges. Then vertices in the cube are 8.

2. Answer: (b) 12

Explanation: In geometry, a cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. The cube is the only regular hexahedron and is one of the five Platonic solids. It has 6 faces, 12 edges, and 8 vertices.

3. Answer: (c) 6

Explanation: Cube is a 3D solid object bounded by six square faces with three meeting at each vertex. Hence a cube has 6 faces.

4. Answer: (a) 250 cm²

Explanation: Edge of the cube =5 cm

After joining two cubes,

Total length, l=5+5=10cm

Breadth, b=5cm   and 

Height, h=5cm

∴   Surface Area =2(lb+bh+lh)

= 2(10×5+5×5+5×10)

= 2×125

=  250 cm²

5. Answer: (b) A brick

Explanation:  A brick has rectangles as its horizontal and vertical cross-sections. A round apple has circles as its horizontal and vertical cross-sections. A die has a square and rectangle as its horizontal and vertical cross-sections. A circular pipe has rectangle and circle as its horizontal and vertical cross-sections. Ice cream has a circle and triangle  as its horizontal and vertical cross-sections.

6. Answer: (d) Rectangle

Explanation: Rectangular cross-section obtained if we cut a brick horizontally.

7. Answer: (a) square

Explanation: Because when we see from the overhead projector in dark we will get a square as the shape of the cube is exact to a square.

8. Answer: (b) 6

Explanation: A rectangular prism is a 3-d solid shape that has 6 rectangular faces in which all the pairs of opposite faces are congruent. It has 8 vertices, 6 faces, and 12 edges. A few real-life examples of a rectangular prism include rectangular fish tanks, shoe boxes, etc.

9. Answer: (a) 4

Explanation: There are no other convex polyhedra other than the tetrahedron having four faces. The tetrahedron has two distinct nets (Buekenhout and Parker 1998).

10. Answer: (c) 6 

Explanation: A cube is a three-dimensional shape having six faces.

11. Answer: (d) Any shape 

Explanation: A pyramid is a polyhedron whose base is a polygon (of any number of sides) and whose lateral faces are triangles with a common vertex.

12. Answer: (b) 8 

Explanation: By Euler’s formula we know that: 

For any polyhedron, F + V – E = 2

F = 2-V+E 

F = 2 – 6+12  

= 8

13. Answer: (c) Polyhedrons 

Explanation: Two important members of polyhedron family are prism and pyramid. A prism is a polyhedron with two congruent bases, in parallel planes, and the lateral sides are rectangles. A pyramid is a polyhedron with one base and all the lateral sides meet at a common vertex. The lateral sides are triangles.

14. Answer: (a) F + V = E + 2 

Explanation: We know that Euler's formula is given as: F +V = E + 2 where F is the total number of Faces in the given solid. V is the total number of the vertices. E is the total number of edges.

15. Answer: (a) A Circle 

Explanation: The base of a right-cone is always circular. When we see it from the top, it looks like a circle with its vertex as the center of the circle.

16. Answer: (c) cone 

Explanation: It has 2 faces → 1 curved face and 1 flat face. It has 1 curved edge. it is Cone.

17. Answer: (c) A rectangle is 2-dimensional and a cube is 3-dimensional 

Explanation: The difference in rectangle and cube is that, a rectangle is a 2-dimensional figure where the length and the breadth of the geometry are specified. A cube is a 3- dimensional figure where the length, breadth and depth of the geometry are specified.

18. Answer: (a) A sphere has one flat surface 

Explanation: Statement(A) is false, as there is no flat surface in a sphere.

19. Answer: (d) Four lateral faces, which are congruent isosceles triangles and a square base

Explanation: All square pyramids have: a square base, four triangular sides, five vertices, eight edges. A square pyramid can be called a pentahedron because it has five faces: four triangle faces and one square face.

20. Answer: (c) Rectangle 

Explanation: Triangular prisms are three-dimensional figures formed by putting rectangles and triangles together. The bases are triangles. So, the lateral faces are formed by rectangles.

21. Answer: (a) length, breadth, height

Explanation: Three-dimensional shapes occupy space and have three demensions.

22. Answer: (b) Cylinder

Explanation: It is a cylinder. When we place 10 coins, which are of circular shape, one over another they form a cylinder.

23. Answer: (a) edge

Explanation: A face is a flat surface. An edge is where two faces meet. A vertex is a corner where edges meet.

24. Answer: (c) 3

Explanation: A cylinder has three faces, two circular faces and one curved face.

25. Answer: (c) 8

Explanation: The square pyramid has the square base and the triangular sides so it has four edges of the square and the four edges of the triangular shape. So, in total a square pyramid has eight edges.
