The volume of three rectangular prisms combined can be a tricky concept to comprehend. The volume of a rectangular prism is calculated by multiplying the length, width and height. So, if we were to combine three rectangular prisms, then the combined volume of all three would be the sum of the volumes of each of the three separate prisms. That being said, if we know the volume of each of the three individual prisms, then we can easily calculate the combined volume of the three prisms.

## Combined Volume of Three Rectangular Prisms

Let’s take an example to understand this concept better. Suppose we have three rectangular prisms, each having a volume of 5, 12 and 18. To calculate the combined volume of these three prisms, we will have to add the three individual volumes together. So, the combined volume of these three rectangular prisms will be 5 + 12 + 18 = 35. In this example, the combined volume of the three rectangular prisms is 35.

## Combined Volume of Three Rectangular Prisms with a Combined Volume of 518

Now, let’s take a different example where the combined volume of the three rectangular prisms is 518. To calculate the individual volumes of the three rectangular prisms, we can use the same method as before. We will have to add the three individual volumes together to get the combined volume. So, if the combined volume is 518, then we can calculate the individual volumes of the three rectangular prisms by solving the equation 5 + x + y = 518. After solving this equation, we can find that the individual volumes of the three rectangular prisms are 223, 135 and 160 respectively.

## Importance of Calculating the Volume of Three Rectangular Prisms

Knowing the combined volume of three rectangular prisms can be useful in several situations. For example, if you are building a structure with three rectangular prisms, then you will need to know the combined volume of the three prisms in order to calculate the amount of materials needed. Similarly, if you are designing a product that consists of three rectangular prisms, then knowing the combined volume of the three prisms will help you design a product that is of the right size and volume. Knowing the combined volume of three rectangular prisms can also be helpful in solving mathematical problems, as it can help you calculate the individual volumes of the three prisms.

In conclusion, the combined volume of three rectangular prisms can be calculated by adding the individual volumes of each prism together. For example, if the combined volume of three rectangular prisms is 518, then the individual volumes of the three rectangular prisms will be 223, 135 and 160 respectively. Knowing the combined volume of three rectangular prisms can be helpful in several situations such as building structures and designing products.
