Volume of Rectangular Prisms

This video tutorial explains how to calculate the volume of rectangular prisms, including those with fractional side lengths. It covers the formula for volume, which is the area of the base times the height, and clarifies the difference between lowercase and uppercase B in formulas. The tutorial provides examples with both whole numbers and fractions, demonstrating how to convert mixed numbers to improper fractions for calculations. It also emphasizes the importance of correct unit labeling and concludes with a final example to reinforce the learning.

What is the formula used to find the volume of a rectangular prism?

• Volume = length + width + height

• Volume = area of the base + height

• Volume = area of the base × height

• Volume = length × width × height

What does the lowercase 'b' represent in the formula for area?

• The height of the rectangle

• The volume of the prism

• The base of the rectangle

• The area of the base

How do you calculate the area of a rectangle?

• Length × Width

• Base × Height

• Length + Width

• Base + Height

Why is it important to understand the difference between lowercase and uppercase 'b'?

• To correctly identify the base of a triangle

• To understand the concept of perimeter

• To differentiate between base and height

• To correctly calculate area and volume

What is the next step after finding the area of the base to calculate volume?

• Multiply by the height

• Divide by the height

• Add the height

• Subtract the height
