![]() ![]() The volume of a rectangular prism is the total amount of space it takes up, and can be defined as the product of its length, width, and height. How to Find the Volume of a Rectangular Prism: Therefore, the surface area of the rectangular prism is 112cm². Plug the figures into the formula for surface area and solve. Solve for Surface Area:įind the surface area of a rectangular prism with the following measurements: Make sure all units are the same before you compute the surface area. Note: Surface areas are expressed in cubic units such as in 2, cm 2, km 2, m 2. Where: l = length of the prism w = width of the prism and h = height of the prism. Use one of these formulas to find the surface area of a rectangular prism: Related Reading: Area of a Rectangle – Formula & Examples Recall that the area of a rectangle is the product of its length and width: A = l ![]() The total surface area of a rectangular prism is the sum of all the areas of its six rectangular sides. How to Find the Surface Area of a Rectangular Prism: Examples of objects shaped like a rectangular prism are shoe boxes, books, buildings, and cabinets. It has a length, width, and height that make up 3 pairs of equal rectangular faces: top-bottom, left-right, and front-back. A cube is a prism, but unlike a cube that has 6 equal square faces, a rectangular prism has six rectangular faces and 12 edges. ![]() Prisms are three-dimensional objects with two equal bases or ends, flat surfaces or sides, and the same cross-section along its length. The boxes- you can fit 12 crates in the boxcar.Let’s learn how to find the surface area and volume of a rectangular prism. Little bit easier to kind of just visualize You think about it- I find this one to be a The boxcar than the crate? Well, what's 180 divided by 15? Well, it's exactly 12. Well, 1.5 times 2 is 3, timesĥ is 15, so 15 cubic meters. We just figured out, is 5 times 1.5 times 2. If we do our math right, it should come out Volume of the crate? Well, the crate volume. So there's 15 meters timesģ meters times 4 meters. How much larger the boxcar is, how many times larger. So we could figure out theĭimensions of the boxcar, then the dimensions of the crate. Times the volume of one of the crates, ifĭimensions, you might not be able to squeeze exactlyġ2 crates in there. Because if theĭimensions aren't right, even if the boxcar is 12 This way more, just to make sure that theĭimensions actually work out, so that you couldĪctually squeeze these in. More is the volume of the box car than the crate? I like doing it Now, another way you could haveĭone it is you could say, OK, they're telling us that And then you could fit 2Īlong the height, so times 2, gets us to 3 times 2Ĭrates in the boxcar. 1.5 and 1.5 gets you toģ meters, so times 2. So you could fit 1,Ģ, 3 along the length. The number of crates that could fit inside. Multiply those three numbers, we would have counted How many can you fit in thisĭirection along the length? How many can youįit along the width? And how many can youįit along the height? And essentially, if we Think about how many crates you could fit in a boxcar. Wide for a boxcar, and then it is 4 meters high. We can see what's going on behind the scenes. So you could fit three of theĬrates along an edge like that. So that this wholeĭistance would be 5 meters, and then another 5 meters here,Īnd then another 5 meters here. And they give us theĭimensions of the boxcar. Long, and 1.5 meters wide, and has a height of 2 meters. To fit inside the boxcar with their bases facing down. In rectangular crates and hire a boxcar to ship theĬrates across land and sea. ![]()
