Volume and surface area · Grade 5
In Grade 5 you learn: volume by counting cubes and volume of cuboids.
Volume is how much space a solid takes up, measured in cubic units; surface area is the total area of all its faces. For any prism (including cuboids and cylinders) the volume is the area of the cross-section times the length.
Key facts
