| Cuboid | 2(lb+bh+hl) Where, l = length, b = breadth and h = height | Length x Width x Height |
| Prism | ph+2B Where p= perimeter of the base, h = height and B =area of the base | Area of base x Height |
Also, What is surface area examples?
The total area of the surface of a three-dimensional object. Example: the surface area of a cube is the area of all 6 faces added together.
Hereof, Is surface area and volume the same?
Surface area is a two-dimensional measure, while volume is a three-dimensional measure. Two figures can have the same volume but different surface areas. For example: … A rectangular prism with side lengths of 1 cm, 1 cm, and 4 cm has the same volume but a surface area of 18 sq cm.

Why do we calculate surface area?
The surface area of a three-dimensional object is the total area of all of its surfaces. Surface area is important to know situations where we want to wrap something, paint something, and eventually while building things to get the best possible design.
Is surface area the same as area?
Area vs Surface Area
The area is the measurement of the space occupied by any two-dimensional geometric shapes. The surface area is the sum of areas of all the faces of the three-dimensional figure. Plane 2D figures represent the area. Example: circles, rectangles, and triangles.
What are three major differences between surface area and volume?
The Surface Area is a 2-Dimensional concept with units m², cm² or mm² whereas Volume is a 3-Dimensional concept with m³, cm³ or mm³ as units. Surface Area can be found for 2-D figures like Circle, Square, Rectangle but Volume cannot be found for them.
Which is bigger volume or surface area?
The surface area is greater than the volume, and less than the volume, just depending on what units we use.
What is the difference between total surface area and curved surface area?
The term surface area is defined as the total area of the surface of the given solid object. … Curved Surface Area (CSA) – It includes the area of all the curved surfaces. Lateral Surface Area (LSA) – It includes the area of all the surface excluding the top and bottom areas.
What is surface area and volume of 3D shapes?
The surface area of a 3D shape is the total area of all its faces. • Volume of a pyramid = 1. 3. × area of base × vertical height.
What are the most common surface area?
This Section will discuss the calculation of some of the most common surface areas: the triangle,
the square
, the rectangle, the rhombus, the parallelogram, the trapezium and the circle (see Fig. 1a).
…
What is the surface area of square?
As the area of a square is the product of the length of its sides, the final formula for the surface area of a cube is: A = 6 * l² , where l is a square side.
What is the surface area of a rectangle?
To find the area of the rectangle, just multiply the two edges together. Area (bottom edge) = length times width = lw. Going back to our example, the area of the bottom face is 4 inches x 3 inches = 12 square inches.
What is difference between total surface area and curved surface area?
Curved Surface Area (CSA) – It includes the area of all the curved surfaces. Lateral Surface Area (LSA) – It includes the area of all the surface excluding the top and bottom areas. Total Surface Area (TSA) – It includes the area of all the surfaces of the object including the bases.
What’s the difference between surface area and volume?
Surface area is a two-dimensional measure, while volume is a three-dimensional measure. Two figures can have the same volume but different surface areas. For example: … A rectangular prism with side lengths of 1 cm, 1 cm, and 4 cm has the same volume but a surface area of 18 sq cm.
What is difference between total surface area and lateral surface area?
The lateral surface area is the area of all sides excluding the area of the base. Total surface area of any solid is the sum of areas of all the faces of the solid.
What is the difference between surface area and area?
The area is the measurement of the space occupied by any two-dimensional geometric shapes. The surface area is the sum of areas of all the faces of the three-dimensional figure. Plane 2D figures represent the area.
What is difference between area and volume?
An area is a two-dimensional object whereas volume is a three-dimensional object. The area is a plain figure while volume is a solid figure. The area covers the outer space and volume covers the inner capacity. The area is measured in square units and volume is measured in cubic units.
What is surface area and volume?
The surface area of any given object is the area or region occupied by the surface of the object. Whereas volume is the amount of space available in an object. In geometry, there are different shapes and sizes such as sphere, cube, cuboid, cone, cylinder, etc.

What is surface area volume?
The surface-area-to-volume ratio, also called the surface-to-volume ratio and variously denoted sa/vol or SA:V, is the amount of surface area per unit volume of an object or collection of objects.
Where do we use total surface area?
For a two-dimensional object, that’s also its total surface area. In three dimensions, like a cube, a sphere, or a pyramid, the surfaces can’t all be seen at one time. Total surface area in that case means adding up the areas of all the surfaces. For a cube, that means adding up the surface area of all six sides.
What is the difference between area and surface area of a cube?
Area is the space or the region occupied by any flat two-dimensional shape. Surface area is the area or the space occupied by the lateral surface and the area of all the faces of a three-dimensional shape.
Where is curved surface area used?
The curved surface area refers to the area of only the curved part of a 3D figure. In general, the lateral surface area and curved surface areas are the same in meaning. For example: In cuboid we use lateral surface area whereas in case of cylinder its curved surface area when you exclude its top and base surfaces.
