The lateral surface of an object is all of the sides of the object, excluding its base and top (when they exist). The lateral surface area is **the area of the lateral surface**. For a right circular cylinder of radius r and height h, the lateral area is the area of the side surface of the cylinder: A = 2πrh.

## How do you find the lateral area?

Lateral indicates the side of something. Therefore, lateral surface area is found by finding the surface area of the sides of the object. This is done by finding the perimeter of the base and multiplying it by the height of any three-dimensional figure.

## How do you find the lateral area and surface area?

To find the surface area of the solid, add the areas of all polygons in the net, including both the bases and the lateral faces. To find the lateral area of the solid, find the sum of the areas of only the lateral faces.

## What is lateral and total surface area?

The total surface area of a solid is the sum of the areas of all of the faces or surfaces that enclose the solid. The lateral surface area of a solid is the surface area of the solid without the bases. Imagine a soup can. Cut off the top and the bottom.

## What is base area?

It refers to the area of one of the bases of a solid figure. It can be used to determine the volume of solid figures.

## What is the lateral area of the prism?

The lateral area of a figure is the area of the non-base faces only. When a prism has its bases facing up and down, the lateral area is the area of the vertical faces. (For a rectangular prism, any pair of opposite faces can be bases.)

## What is the shape of the lateral area?

The lateral area of a square pyramid is defined as the area covered by its slant of lateral faces. A pyramid is a three-dimensional object whose base can be any polygon whereas its side faces are all congruent triangles. One side of each of these triangles coincides with one side of the base polygon.

## Where is lateral surface area used?

The lateral area formula is used to find the lateral area of any solid object. The lateral area of any figure is the area of the non-base faces only. Lateral area formulas help in calculating the lateral surface area of different figures including cuboid, cube, cylinder, cone, and sphere.

## What is the lateral area of a cube?

The lateral area of a cube can be calculated, given the length of the diagonal. The formula to calculate LSA, in this case, is given as, LSA = 4d^{2} / 3, where d is the space diagonal of the cube.

## What is the lateral area of the figure of rectangular prism?

The lateral surface area of any right rectangular prism is equivalent to the perimeter of the base times the height of the prism. Therefore, the lateral surface area of a rectangular prism = 2 ( l + w ) h square units.

## What is the lateral area of a right triangular prism?

The lateral surface area of the right triangular prism (LSA) = ah + bh + ch (or) (a + b + c) h, where a, b and c are the bases of the rectangular faces and h is the common height or the total height of the prism. Also, (a + b + c) is the perimeter of the base (triangle).

## How do you find the area of lateral faces?

The area of the 4 lateral faces is found by adding the widths of all of the individual faces, the perimeter (P) of the base of the pyramid, and then multiplying by the height of the triangle, which is the slant height, l, of the pyramid.
