Calculating Volume of Composite Prisms

This video tutorial explains how to find the volume of composite rectangular prisms by breaking them down into individual rectangular prisms and adding their volumes. Two examples are provided, demonstrating different ways to divide the prisms and calculate their volumes step-by-step. The video concludes with a summary of the methods used.

What is the first step in finding the volume of a composite rectangular prism?

• Calculate the surface area

• Break it down into individual rectangular prisms

• Find the perimeter

• Measure the diagonal

In the first example, what is the length of the first rectangular prism?

• 4 feet

• 6 feet

• 5 feet

• 9 feet

How do you calculate the volume of a rectangular prism?

• Length x Width x Height

• Length x Width

• Length + Width + Height

• Width x Height

What is the total volume of the first composite rectangular prism?

• 330 cubic feet

• 60 cubic feet

• 300 cubic feet

• 270 cubic feet

In the second example, what is the length of the first rectangular prism?

• 10 feet

• 15 feet

• 12 feet

• 13 feet

What is the volume of the first rectangular prism in the second example?

• 117 cubic feet

• 130 cubic feet

• 100 cubic feet

• 150 cubic feet

What is the width of the second rectangular prism in the second example?

• 6 feet

• 3 feet

• 4 feet

• 5 feet

What is the total volume of the second composite rectangular prism?

• 160 cubic feet

• 150 cubic feet

• 177 cubic feet

• 200 cubic feet

What is the final step in finding the volume of a composite rectangular prism?

• Subtract the volumes

• Divide the volumes

• Multiply the volumes

• Add the volumes of individual prisms

What is the purpose of dividing a composite rectangular prism into smaller prisms?

• To measure the height

• To calculate the diagonal

• To find the surface area

• To simplify the calculation of volume
