This video tutorial by Mr. J explains how to find the volume of a rectangular prism. It begins with an introduction to the concept of volume and the formula used for prisms. The video then provides two examples of calculating the volume of rectangular prisms, emphasizing the importance of correctly identifying the dimensions of length, width, and height. The tutorial concludes with a summary of the key points covered.

What does volume measure in a 3D object?

• The amount of space it occupies

• The weight

• The perimeter

• The surface area

Which formula is used to calculate the volume of a rectangular prism?

• Volume = Length x Width

• Volume = (Length + Width) x Height

• Volume = Length + Width + Height

• Volume = Length x Width x Height

Why is it not crucial to distinguish between length and width when calculating volume?

• Because length and width are interchangeable in the formula

• Because only the height affects the volume

• Because the volume is always constant

• Because the base area calculation does not require it
