## What is Surface Area? Definition & Formulas Description

Surface area of three-dimensional solids refers to the measured area, in square units, of all the surfaces of objects like cubes, spheres, prisms and pyramids.

This course will define and explain what total surface area is and provide the formulas for calculating total surface area, as well as an explanation about why they work.

Surface area means all the area that you can see in two dimensions - this means the length and width. The surface area of a wall is everything you can paint. The surface area of a floor is everything you can walk on. So, the surface area of a rectangle, circle, triangle, or other shape is simply a measurement of everything within the lines of the shape. 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. For a sphere like a baseball, you want to know how much area the leather casing measured.

When thinking about an object, there are only three ways of measuring its size - perimeter, area, and volume. With perimeter, you are thinking about the distance around the edges of the object. So if you had a square and wanted to know its perimeter, you would measure how long each side was, and then add up your total measurements. Because you would be measuring distance, your result would simply be in meters or feet, a one-dimensional result. For example, with four sides that are each ten meters long, you would have a perimeter of 40 meters.

For area, you would want to know the total surface area, or amount of space within the perimeter. Returning to the square, you would want to measure its two-dimensional size. To do that, you would multiply the length by the width. Your answer would still be in length units, like meters or feet, but now it would be a measurement squared, representing that it was two dimensions

#### Q. I’m unable to make a payment. What to do now?

You can try to make the payment through a different card or account (maybe a friend or family). If the problem persists, email us at info@easyshiksha.com

At times, there may be a slight delay in your payment reflecting on your EasyShiksha dashboard. However, if the problem is taking longer than 30 minutes, please let us know by writing to us at info@easyshiksha.com from your registered email id, and attach the screenshot of the payment receipt or transaction history. Soon after verification from the backend, we will update the payment status.

#### Q. What is the refund policy?

If you have enrolled, and are facing any technical problem then you can request a refund. But once the certificate has been generated, we shall not refund that.

#### Q.Can I just enrol in a single course?

Yes! You surely can. To begin this, just click the course of your interest and fill in the details to enrol. You are ready to learn, once the payment is made. For the same, you earn a certificate too.
