The standard
Calculate the volume of right rectangular prisms with fractional edge lengths by applying the formula, V = (area of base) x (height).
Element 6.GSR.5.3 of Georgia's K-12 Mathematics Standards (2021, effective SY2023-24), in the Geometric & Spatial Reasoning strand. It sits under standard 6.GSR.5: Solve relevant problems involving area, surface area, and volume.
What students practice
Students pack a box with cubes of edge one half or one third, multiply the area of the base by the height, and find one missing edge. Every item has a fractional edge, and those denominators are 2, 3, and 5. Contexts fill, pack, or hold. There is no volume displacement.
Where to find it
Think: surface area adds the faces; volume multiplies 3 edges.
