The 3 on the unit represents volume.Īlso, this site have free math lessons on volume of solids that may be of interest to you (scroll down page the see the list of lessons). Similarly, for rectangular prism with 5 inches in height, 4 inches in width, and 3 inches in depth, we can calculate its volume as follows:Īpplying the same logic, since we are multiplying three lengths with unit the inches together, logically, we can write the resulting unit as inch 3 (cubic inches). As for the unit, since we are multiplying two lengths with the unit inches together, logically, we can write the resulting unit as inch 2 (square inches). To calculate the numbers (2 × 3 = 6) is the easy part. What is Rectangular Prism Rectangular Prism is a 3-D shape, which has six faces, 8 vertices, and 12 edges. To answer this, let's say we have a square that the width of 2 inches and the length of 3 inches, we can calculate its area as follows: Before writing the program of calculating the volume of a rectangular prism in different programming languages, firstly we have to know about the rectangular prism and its volumes formula. Next, if we can represent length with the unit inch, how do we represent the unit for area? Now, if I tell you the number is in inches (1 inch), you will know that the number represents length. In your mind, you know that it is just a number and it does not have much meaning. Since the base of a rectangular prism is a rectangle, its area will be l × w. Imagine that you are given a number, let's say 1. The formula for the volume of a rectangular prism base area × height of the prism. And so our area for our shape is going to be 44. So this is going to be 32 plus- 1/2 times 8 is 4. So once again, lets go back and calculate it. As for the units, you can find it by following the logic below: Volume of a triangular prism formula offerup request failed with status code 410 The triangles height is 3. The volume of each prism is obtained with the mathematical formula seen in the first point, which consists of multiplying the base by the height and by the length.ĭepending on the shape of the room, it will be more or less difficult to calculate its volume.AnswerThe calculated number 60 (W×L×H = 4×3×5) is correct. Volume of the room = volume prism 1 + volume prism 2 What we have done is to divide the room into two rectangular prisms, so we will calculate the volume of each one and, finally, we will obtain the total volume of the room by adding the results obtained. Below we can see an L-shaped room, how do we calculate its volume? in this case? The problem with measuring the volume of a room is that its shape is usually not perfectly square or rectangular. That is, we will have to measure the height, width and length of the room in meters to calculate how many cubic meters fit in the room. To calculate the volume of a rectangular prism, multiply the area of the. Calculate the volume of a roomįor calculate the volume of a room we have to make the same calculation that we have seen in the previous point. measure of capacity and is measure in cubic units. decomposing the figure into two rectangular prisms and adding their volumes. Now that you know a little more about the parallelepiped and know how to calculate its volume from the formula, let's look at more particular cases. The volume of a rectangular prism is given by V l× w × h, and the volume. Problem 7: Determine the volume of a rectangular prism if its height is 10 cm and its base length and width are 8 cm and 6 cm, respectively. In this case, the cubic units typically used are cm3, m3, in3, and others. The unit of volume can be denoted by cubic unit. The amount of space a rectangular prism has occupied is its volume. Hence, the volume of a rectangular prism is 3600 cubic units. The area of Rectangular prism can be calculated by the following formula: (S) 2 (lw + lh + wh). It has six faces, all of them parallel and equal in sets of two by two. The volume of a rectangular prism l × w × h cubic units.If you want to know more about the parallelepiped or rectangular prism, you should know that: Similarly,you can try the volume of rectangular prism calculator to find the volume of the following rectangular prisms for the following measurements. Solution: Volume of rectangular prism l × w × h 4 × 8 × 10 320 cubic units. In our example, since we have all dimensions in centimeters, the result is measured in cubic centimeters. Find volume of rectangular prism whose length is 4 units and width is 8 units and height is 10 units. It is important that you always write down the units of volume in the result. To calculate its volume, we simply have to multiply its dimensions applying the following formula:įor example, let's calculate the volume of the rectangular prism above:
