Estimating answers (age 10+)
Find the volume of right rectangular prisms by packing with unit cubes and show it equals l × w × h (or base area × height); apply V = l × w × h and V = B × h to solve real-world problems; calculate, estimate, and compare volumes of cubes and cuboids in standard units (cm³, m³)

Full guide and materials
- Activity. Find the volume of right rectangular prisms by packing with unit cubes and show it equals l × w × h (or base area × height); apply V = l × w × h and V = B × h to solve real-world problems; calculate, estimate, and compare volumes of cubes and cuboids in standard units (cm³, m³)
What to notice. Use V = l × w × h to find the volume of a cuboid 4 cm × 3 cm × 5 cm = 60 cm³ • Explain why packing a prism with unit cubes gives the same result as multiplying edge lengths • Compare volumes of two cuboids and identify which has greater capacity
