Calculating the volume of rectangular prisms is a new skill that is introduced in 5th grade. Students will apply mathematical formulas to find the volume of different kinds of figures and also determine the volume of a figure composed of two connected rectangular prisms. Learners will also work with other kinds of measurement when they make larger or smaller versions of figures (to scale) and learn to convert measurements.
