(209).jpg "Identify The Basic 3D Shapes: Quiz! - Quiz")
A 3D shape is represented by its edges, faces, and vertices, measured in 3 directions, known as three-dimensional shapes. The length, width, and height are the three measuring units ina 3D shape. Take this quiz to test your knowledge about different 3D shapes. All the best!
Questions and Answers
- 1.
What shape is a 3d circle?
- A.
Cube
- B.
Rectangle
- C.
Circle
- D.
Sphere
Correct Answer
D. SphereExplanation
A 3D circle does not exist as a shape. A circle is a 2D shape, so it only has two dimensions - length and width. A sphere, on the other hand, is a 3D shape that has three dimensions - length, width, and height. Therefore, a sphere is the closest shape to a 3D circle because it is a round object in three dimensions.Rate this question:

What shape is the cross-section of the sphere?
- A.
Cone
- B.
Circle
- C.
Pyramid
Correct Answer
B. CircleExplanation
The cross-section of a sphere is always a circle. A sphere is a three-dimensional object with all points on its surface equidistant from its center. When a plane intersects a sphere, the resulting cross-section is a circle. This is because a circle is a two-dimensional shape with all points equidistant from its center, just like the surface of a sphere. Therefore, the correct answer is circle.Rate this question:

What kind of shape will you get with a cross-section parallel to the base?
- A.
Cylinder
- B.
Circle
- C.
Cube
Correct Answer
B. CircleExplanation
A cross-section parallel to the base of a cylinder will result in a circle. This is because a cylinder has a circular base, and any cross-section that is parallel to the base will have the same shape as the base, which is a circle.Rate this question:

Will the cross-section be congruent to the base of a cylinder.
- A.
No
- B.
Yes
Correct Answer
A. NoExplanation
The cross-section of a cylinder is a circle, while the base of a cylinder is also a circle. Since the question asks if the cross-section will be congruent to the base, and the answer is "no," it implies that the cross-section is not a circle and therefore not congruent to the base.Rate this question:

What is a description of a cone?
- A.
A figure with a circle top
- B.
A figure with a pointed top and a circled bottom
- C.
A figure with a square top
Correct Answer
B. A figure with a pointed top and a circled bottomExplanation
A cone is a three-dimensional geometric shape that has a pointed top and a circular base. The pointed top is called the apex, and the circular base is the bottom of the cone. The shape of a cone resembles that of an ice cream cone or a traffic cone.Rate this question:

A 3-D shape can also be called...
- A.
A flat shape
- B.
A solid shape
- C.
A polygon
- D.
A quadrilateral
Correct Answer
B. A solid shapeExplanation
A 3-D shape can also be called a solid shape because it has three dimensions - length, width, and height. Unlike flat shapes, which only have two dimensions, solid shapes have volume and take up space in three-dimensional space. Solid shapes can be seen and touched from different angles, and they have depth. Therefore, the term "solid shape" accurately describes a 3-D shape.Rate this question:

Vertices are also called...
- A.
Edges
- B.
Corners
- C.
Faces
- D.
Sides
Correct Answer
B. CornersExplanation
Vertices are points where two or more edges meet in a geometric shape. In two-dimensional shapes, such as polygons, vertices are commonly referred to as corners. Therefore, the correct answer is "Corners".Rate this question:

A solid object has six faces which are all squares. What is the name of this object?
- A.
Cube
- B.
Cuboid
- C.
Cylinder
- D.
Rectangle
Correct Answer
A. CubeExplanation
A cube is a solid object that has six faces, all of which are squares. Therefore, the correct answer is Cube.Rate this question:

Which 3-D shape has six rectangular faces?
- A.
Sphere
- B.
Cuboid
- C.
Cylinder
- D.
Square
Correct Answer
B. CuboidExplanation
A cuboid is a 3-D shape that has six rectangular faces. It is similar to a rectangular prism, with opposite faces being equal in size and shape. The rectangular faces of a cuboid make it different from other shapes like a sphere, cylinder, or square, which do not have six rectangular faces. Therefore, the correct answer is cuboid.Rate this question:

Most dice are the shape of which 3-D shape?
- A.
Cuboid
- B.
Cylinder
- C.
Cube
- D.
Square
Correct Answer
C. CubeExplanation
A cube is a three-dimensional shape with six equal square faces. Most dice are shaped like cubes, with each face having a different number of dots or pips. This shape allows for equal probability of landing on any face when rolled, making it ideal for games of chance.Rate this question:
