This video tutorial covers the calculation of volume for various 3D figures, including rectangular prisms, right triangular prisms, pyramids, cylinders, cones, and spheres. Each section explains the formula used to find the volume, emphasizing the importance of understanding the base area and height for prisms and cylinders, and the unique formulas for pyramids, cones, and spheres. Practice problems are provided for each type of figure to reinforce learning.

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

• Volume = Length / (Width x Height)

• Volume = (Length x Width) / Height

• Volume = Length x Width x Height

• Volume = Length + Width + Height

Why is the volume of a pyramid divided by 3 in its formula?

• To simplify the calculation

• Because it's a third of the volume of a prism with the same base and height

• To account for its triangular base

• Because it has 3 sides
