1. Which types of prism does the 3rd figure represents?
a) Triangular
b) Square
c) Pentagon
d) Oblique
Explanation: A solid (3-dimensional) object which has six faces that are rectangles. It has the same cross-section along a length, which makes it a prism. It is also a “cuboid”.
2. Which types of prism does the 6th figure represents?
a) Triangular
b) Square
c) Pentagon
d) Oblique
Explanation: A prism with bases that are not aligned one directly above the other. Note: The lateral faces of an oblique prism are parallelograms.
3. Which types of prism does the 2nd figure represents?
a) Triangular
b) Square
c) Pentagon
d) Oblique
Explanation: A square prism is a three-dimensional shape with two square bases and flat sides. Therefore, all square prisms consist of at least two squares, even if not all the sides are squares, as long as the bases are square, there is a square prism. Cubes are a common example of squareprisms.
4. Which types of prism does the 5th figure represents?
a) Triangular
b) Square
c) Pentagon
d) Rectangular
Explanation: In geometry, a cuboid is a convex polyhedron bounded by six quadrilateral faces, whose polyhedral graph is the same as that of a cube. While mathematical literature refers to any such polyhedron as a cuboid, other sources use “cuboid” to refer to a shape of this type in which each of the faces is a rectangle (and so each pair of adjacent faces meets in a right angle); this more restrictive type of cuboid is also known as a rectangular cuboid, right cuboid, rectangular box, rectangular hexahedron, right rectangular prism, or rectangular parallelepiped.
5. Which types of prism does the 1st figure represents?
a) Triangular
b) Square
c) Pentagon
d) Equilateral triangular
Explanation: In geometry, a triangular prism is a three-sided prism; it is a polyhedron made of a triangular base, a translated copy, and 3 faces joining corresponding sides. A right triangular prism has rectangular sides, otherwise it is oblique.
6. Which types of prism does the 4th figure represents?
a) Triangular
b) Hexagonal
c) Pentagon
d) Oblique
Explanation: The hexagonal prism is a prism with hexagonal base. This polyhedron has 8 faces, 18 edges, and 12 vertices. Since it has eight faces, it is an octahedron. However, the term octahedron is primarily used to refer to the regular octahedron, which has eight triangular faces.
7. What does the dotted line in the centre of the figure represents?
a) Axis
b) Vertical line
c) Separation line
d) Centre line
Explanation: It is the imaginary line connecting the end faces is called axis, also a line, used as a reference to determine position, symmetry and rotation is called axis and is shown in figure below. It can be of four types- a) In coordinate geometry and trigonometry as y, x and z axis, b) Axis of symmetry, c) Axis of a solid and d) Axis of rotation.
8. When the prism is placed vertically on one of its end faces, the end face on which the prism rests is called the ________ and the vertical side faces are the ________ faces.
a) bottom, lateral
b) base, lateral
c) base, longitudinal
d) horizontal, lateral
Explanation: When the prism is placed vertically on one of its end faces, the end face on which the prism rests is called the base and the vertical side faces are the lateral faces.
9. When the axis of the pyramid is perpendicular to its base, which pyramid does it represent?
a) Perpendicular pyramid
b) Square pyramid
c) Oblique pyramid
d) Right pyramid
Explanation: A right pyramid is a pyramid with a base that is a regular polygon and whose apex is directly above the centre of the base. The surface area of a right pyramid can be calculated, using. the following formula: SA 5 B 1. Ps, where B is the area of the base, P is the perimeter of the base, and s is the slant height.
10. On projection of a cylinder on a plane, the shape appeared by front view will be _____________
a) line
b) square
c) point
d) rectangle
Explanation: On projection of a cylinder on a plane, the shape appeared by front view will be rectangle
