The video tutorial explains how to find the volume of complex rectangular prisms by deconstructing them into simpler prisms and using the volume formula. It highlights common mistakes, such as overgeneralizing the formula and forgetting hidden layers. The tutorial also presents an alternative method using subtraction to find the volume. Through examples, it demonstrates both methods, emphasizing the importance of understanding different approaches to solve volume problems.

What is a common mistake students make when calculating the volume of complex rectangular prisms?

• They add instead of multiply the dimensions.

• They forget to multiply the dimensions.

• They use the wrong units for volume.

• They count the faces instead of the volume.

How can you find the volume of a complex figure by deconstructing it?

• By dividing it into smaller cubes and adding their volumes.

• By multiplying all dimensions together.

• By counting the number of faces.

• By using the surface area formula.

In the example given, what is the volume of the green cube?

• 16 cubic units

• 12 cubic units

• 8 cubic units

• 4 cubic units

What is the total volume of the complex prism when using the subtraction method?

• 40 cubic inches

• 32 cubic inches

• 24 cubic inches

• 16 cubic inches

When enclosing a complex prism in a larger prism, what is the first step?

• Count the number of smaller prisms.

• Subtract the volume of the missing piece.

• Calculate the surface area of the larger prism.

• Find the volume of the larger enclosing prism.
