Answer: The major types of solid shapes are: **cubes, cuboids, prisms, pyramids, platonic solids, torus, cone, cylinder, and sphere**.

**A 2D shape has two dimensions- length and breadth.** **A 3D shape has three dimensions- length, breadth and height**.

**A sphere is a solid figure** that has no faces, edges, or vertices. This is because it is completely round; it has no flat sides or corners. A cone has one face, but no edges or vertices. Its face is in the shape of a circle.

Vertices, edges and faces**A face is a flat surface**. An edge is where two faces meet. A vertex is a corner where edges meet. The plural is vertices.

A circle is a **round shaped figure that has no corners or edges**. In geometry, a circle can be defined as a closed, two-dimensional curved shape.

**Three-dimensional solids are unlike the shapes as they have a third dimension or thickness**. Three-dimensional solids have width, depth, and height. Solids include cubes, cylinders, spheres, and cones (TEKS K.

**Objects that occupy space** are called solid shapes. Their surfaces are called faces. In simpler words, we can say that faces meet at edges and the edges meet at vertices. Some examples of types of solid shapes are Cone, Cuboid, Sphere, Cube and Cylinder. 2.

combinatorics. Euler was the first to investigate in 1752 the analogous question concerning polyhedra. He found that **υ − e + f = 2** for every convex polyhedron, where υ, e, and f are the numbers of vertices, edges, and faces of the polyhedron.

**Classifying Solid Figures**

- Solid figures are three-dimensional objects, meaning they have length, width, and height.
- The flat surfaces of a solid figure are its faces, or sides as they are commonly called.
- A sphere is a solid figure that has no faces, edges, or vertices.
- A cone has one face, but no edges or vertices.

**Properties of Solid Shapes:**

- Solid figures are basically three-dimensional objects, which means that they have length, height and width.
- Because solid figures have three dimensions, they have depth and take up space in our universe.

**Let's define each part.**

- A face is any flat surface. The flat surface that makes the front of this cube is called a face.
- An edge is the line segment where two faces meet. You can see by looking at this cube that the faces intersect in a line.
- A vertex is a point where several planes meet in a point.

Answer: The major types of solid shapes are: **cubes, cuboids, prisms, pyramids, platonic solids, torus, cone, cylinder, and sphere**.

It can also be called a cuboid. **A cube and a square prism are both special types of a rectangular prism**. Keep in mind, a square is just a special type of rectangle! Cubes are rectangular prisms where all three dimensions (length, width and height) have the same measurement.

length, width and height

Levorotatory (l; (-)): A substance that rotates plane polarized light in a **counterclockwise direction**.

**1 Answer**

- Draw the bond-line structure for 1,3-dibromopentane. Bond-Line.
- Identify the chiral centres. The only chiral centre is C-3 .
- Calculate the number of possible stereoisomers. The maximum number of stereoisomers is 2n , where n is the number of chiral centres.
- Draw the stereoisomers.
- Check for meso isomers.

Nozzle efficiency is **the ratio of isentropic enthalpy drop to actual enthalpy drop, between the same pressures**. Explanation: Nozzle efficiency is defined as the ratio of actual enthalpy drop to isentropic enthalpy drop between the same pressures. 12.

**Characteristics**

- A solution is a homogeneous mixture of two or more substances.
- The particles of solute in a solution cannot be seen by the naked eye.
- A solution does not cause beams of light to scatter.
- A solution is stable.
- The solute from a solution cannot be separated by filtration (or mechanically).

Hint: We are given two rational numbers and we need to find out the greatest rational number between them. For that, we will **Take LCM of all the rational numbers and after that compare its numerator**. The rational number with a greater numerator will be the greatest rational number.

Heredity is best defined as. **The process by which organisms pass on genetic traits to their offspring**.

1 Answer. Living things are made of elements, especially C, H, O, N, P, and S. **Living things are alive because of the chemical reactions that occur in their cells, such as cellular respiration and protein synthesis, among many others.**
