Unit 9 Section 4 : Surface Area and Volume of 3-D Shapes

The bodies occupying space i. The measure of space occupied by a solid-body is called its volume. The units of volume are cubic centimeters written as cm3 or cubic meters written as m3. Remark : A rectangular room is in the form of a cuboid and its 4 walls are its lateral surfaces. Cube : A cuboid whose length, breadth and height are all equal, is called a cube. A cube has 6 faces, each face is square, 12 edges, all edges are of equal lengths and 8 vertices.

Surface Area Formulas and Volume Formulas of 3D Shapes

A sphere is the shape of a basketball, like a three-dimensional circle. Just like a circle, the size of a sphere is determined by its radius, which is the distance from the center of the sphere to any point on its surface. The formulas for the volume and surface area of a sphere are given below. Showing where these formulas come from, like we did for a rectangular solid, is beyond the scope of this course. A globe of Earth is in the shape of a sphere with radius 14 centimeters. Find its a volume and b surface area. Round the answer to the nearest hundredth.

In this section we calculate the volume and surface area of 3-D shapes such as cubes , cuboids , prisms and cylinders. The total surface area is therefore. Giving your answers correct to 3 significant figures, calculate the volume and total surface area of each of the following cylinders:. The diagram shows a wooden block that has had a hole drilled in it. The diameter of the hole is 2 cm. Calculate the volume of this solid, giving your answer correct to 2 decimal places. A concrete beam is to rest on two concrete pillars.

Volume Formulas

If you are a student of class 9 who is using ncert textbook to study maths then you must come across chapter 13 surface area and volumes. It has lot of problems to be solved. Maths formulas of surface area and volume for class 9. For calculations lateral surface area means curved surface area.

Surface area is the area occupied by the surface of the 3-D objects while Volume is the space occupied by the object. Many times 3-D Figure will be the combination of the standard figure so we just need to calculate the surface area and volume separately and then add them. The formulas are given for the following.

Surface area formulas and volume formulas appear time and again in calculations and homework problems. Pressure is a force per area and density is mass per volume. These are just two simple types of calculations that involve these formulas. This is a short list of common geometric shapes and their surface area formulas and volume formulas. A sphere is a solid figure where every point on the surface is equidistant from the center of the sphere.

Аккуратно, предмет за предметом, перетряхнул одежду. Затем взял ботинки и постучал каблуками по столу, точно вытряхивая камешек. Просмотрев все еще раз, он отступил на шаг и нахмурился. - Какие-то проблемы? - спросил лейтенант.
