Objective: Estimate and determine the volume of rectangular prisms with whole number dimensions.
The amount of space inside a three-dimensional figure is the volume of the figure.
Volume (V) is measured in cubic units.
The volume of a rectangular prism is related to its dimensions. Volume (V) = length (l) x width (w) x height (h)
Examples:
V = l x w x h
V = 20 x 14 x 5
20 cm
5 cm
V = 1400 cm
