Surface area — Unlike 2D Shapes, which have only area, 3D shapes have their surface area. It is the total area covered by all the outer surfaces of a 3D Shape. Volume- A three-dimensional shape's volume is the area occupied by a 3D shape or object. It is measured in cubic units and provides insight into the capacity of shapes.
Examples on Surface Area and Volume. Example 1: Find the surface area of a cuboid whose sides are 3cm by 6cm by 10cm. Solution: Surface area of the cuboid is given by: TSA = 2 (16*4 + 14*10 + 10*16) TSA = 2(3 x 6 + 6 x 10 + 3 x 10) TSA = 2(18 + 60 + 30) TSA = 216 cm2. Example 2 Calculate the volume of a cylinder if r = 2.5 cm and h = 4.5 cm
For example, animals in colder habitats have a small surface area to volume ratios (S/V) to conserve maximum heat. In hot areas, animals have a larger surface area to volume ratios to cool their bodies. 7. Digestion and Absorption Of Food. Chewed food has a greater surface area than unchewed food.

Surface Area and Volume Solved Examples. Que 1: Find the lateral surface area of a cylinder with a base radius of 10 cm and height 20 cm. Solution: Given radius r = 10, height h = 20.
Surface Area and Volume of Solids: Surface area is explained as the sum of the areas of all the closed surfaces of a solid.There are three types of surface area: lateral surface area, curved surface area, and total surface area. Volume is a mathematical quantity that defines the capacity of a solid object.
For example, the house that we live in has dimensions. The surface area is the outer part of the figure, whereas volume is the inner part. This article contains solved examples on surface area and volume. Surface Area and Volume Definitions. The complete area of the surface of a three dimensional solid can be termed as surface area.
