Whether you are trying to find out how much wrapping paper you need for a gift or one of many other applications, understanding how to determine a rectangle’s surface area is an essential skill that will prove useful in various situations. In conclusion, calculating the surface area of a rectangle involves identifying the dimensions (length and width), converting units if necessary, and using the simple multiplication formula. So, the surface area of the given rectangle is 50 square inches. The surface area, according to the formula, would be: As a refresher, the surface area of an object is the sum of the areas of all of its faces, or the exterior surfaces of a three-dimensional solid. ![]() Perform the multiplication to find the surface area.Ĭonsider a rectangle with a length of 10 inches and a width of 5 inches. Geometric surface area formulas discuss the lateral surface and the overall surface areas of various geometric solid shapes such as cubes, rectangular prisms, cones, cylinders and other shapes. If they are in different units, convert one into another unit using appropriate conversion factors.Īfter ensuring that both dimensions are in compatible units, plug in values for length and width in the formula. ![]() Total area of top and bottom surfaces is lw + lw. The area of each of the circles is, and the area of the rectangle is calculated by multiplying its length and width to get × 2 2. Recall that all the faces in our calculator are rectangles, and, as mentioned in the rectangle area. Using this formula, multiply the length by the width to find out the surface area of a given rectangular object.Įnsure that both dimensions are in the same unit (e.g., inches, centimeters, meters) before making calculations. The surface area of the above cuboid would be the sum of the area of all the surfaces which are rectangles. Therefore, since the solid has two bases (the bottom one and the top one), the surface area of a rectangular prism formula is as follows: surfacearea 2 × basearea + lateralarea, which, in our notation, translates to. The formula to calculate the surface area of a rectangle is simple: Step 3: Apply the formula for surface area These dimensions can either be given to you or measured using a ruler or measuring tape. The length is typically represented as ‘l’ or ‘L’, while width is represented as ‘w’ or ‘W’. To calculate the surface area, you will need to identify and measure the dimensions – length and width. ![]() Step 2: Identify the measure of length and width The surface area calculation determines how much space is covered by these two dimensions. For a rectangle, this means considering both its length (the longer side) and its width (the shorter side). Surface area refers to the measurement of the total area enclosed by an object in two-dimensional space. Step 1: Understand the concept of surface area In this article, we will walk you through the process of calculating the surface area of a rectangle, step by step. It’s a straightforward formula that measures the extent of an object in two-dimensional space – the product of the length and width of the rectangle. ![]() For example, if you are starting with mm and you know r and h in mm, your calculations will result with V in mm 3 and S in mm 2.īelow are the standard formulas for surface area.Calculating the surface area of a rectangle is a fundamental skill that is frequently used in mathematics, as well as in many real-life scenarios. The units are in place to give an indication of the order of the results such as ft, ft 2 or ft 3. Units: Note that units are shown for convenience but do not affect the calculations.
