The video tutorial by Mr. E covers the concept of volume and introduces two formulas: V = length x width x height and V = big B x little h. The tutorial explains the difference between big B and little b, where big B represents the base area of a 3D figure and little b represents the base of a 2D figure. Through visual examples and problem-solving exercises, students learn when to use each formula and how to calculate volume effectively. The tutorial emphasizes understanding the context of each problem to choose the appropriate formula.

What is the alternative formula for calculating volume introduced in the video?

• V = 2 × (length + width + height)

• V = length × width × height

• V = π × r² × h

• V = B × h

In the context of volume and area formulas, what does a capital B represent?

• The width of a figure

• The base of a 2D figure

• The base of a 3D figure

• The height of a figure

How do you calculate the base area of a 3D figure?

• By adding the length and the width

• By multiplying the length by the width

• By multiplying the length by the height

• By multiplying the height by the width

Which formula is more appropriate for finding the volume of a box with given length, width, and height?

• V = length × width × height

• V = π × r² × h

• V = 2 × (length + width + height)

• V = B × h
