The solid shown below is made by combining two rectangular prisms. What is the volume of the solid?

To find the volume of the solid formed by combining two rectangular prisms, you simply add the volumes of both prisms together. The volume of a rectangular prism is calculated using the formula: Volume = length × width × height. Once you have the dimensions for both prisms, plug in the values, calculate the volumes separately, and then sum them up. Voilà! You have the volume of the combined solid! When working with prisms, it's also vital to double-check the dimensions to ensure they're all in the same units. Common mistakes include mixing up units (like inches and centimeters) or miscalculating one of the prism's volumes. A little extra care can prevent headaches later on!
