What is more, among the four, there are two pairs of identical ones (the front and back wall and the left and right wall). We have four faces contributing to that number, and all of them are rectangles.

Piece of cake, wasn't it? Well, let's now try to do something a little bit more complicated and move on to the lateral area. And that is precisely the formula for the base area: With our notation, it is a rectangle with sides l and w, so its area is l × w. Now, let's use that information to study the base of our prism. Recall that all the faces in our calculator are rectangles, and, as mentioned in the rectangle area calculator, they are calculated by multiplying the side lengths. Surface_area = 2 × base_area + lateral_area, 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: On the other hand, A_l denotes the lateral area, meaning the total area of the four lateral faces. Note that A_b denotes the surface area of a single base of our prism. h – the lateral edge length (also called the height of the prism).

Let's start with the notation we use for them and for the other values in our surface area of a rectangular prism calculator: To see what is the surface area of a rectangular prism, we need to know all three of its sides.

Time to put the high-brow words aside and focus on how to find the surface area of a rectangular prism. Lastly, the sides of each rectangle are called edges (again divided into base edges and lateral edges). The bottom and top faces of the box are called bases, and each of the other four is called a lateral face. Note that this, in particular, means that there are three pairs of identical faces placed on opposite sides of the solid.Īlso, as with any other scientific definition, there are a few fancy names associated with the prism. Well, that is a rectangular prism! Or do you remember those drawings of houses that we did in kindergarten? Remove the angular roof, and you're left with another example of a rectangular prism.įormally (mathematically), a right rectangular prism is a solid where all six sides are rectangles that are perpendicular to one another.

A regular, rectangular box, just like the ones you see in the supermarket, full of whatever products.

Also, in case of any problem where all the values of the trapezoidal prism are given in different units, remember to convert them to a unit that you are comfortable with before proceeding with the calculations.Before we see what the surface area of a rectangular prism is, we should get familiar with the prism itself. Thus, the volume of the prism is 268 cubic centimeters (cc).Īlways remember to use the right units when you find the volume, as sometimes instead of centimeters, even inches and millimeters can be used for expressing the given data. Find the volume of this geometric structure.Īs the actual height is not given, we have to use equation no. The top width is 6 cm, and slant height is 2 cm. Example #2Ī trapezoidal prism has a length of 5 cm and bottom width of 11 cm. Thus, the volume of the prism is 70 cubic centimeters (cc). 1, i.e., the first formula, the expression can be written as: The top and bottom widths are 3 and 2 centimeters respectively. Calculate the volume of a trapezoidal prism having a length of 7 centimeters and a height of 4 centimeters.
