Volume by Counting Cubes — Easy Worksheet 2
Grade 5 · MathSheets Name: ____________________ Date: __________
Each small cube is 1 cubic unit. Read each question carefully and count the cubes, including the ones hidden under or behind others. Every cube sits on the floor or on another cube.
How to solve
Volume is the number of unit cubes that make the solid. For a box, count one layer (length × width) and multiply by the number of layers: 4 × 3 × 2 = 24 cubic units. For a staircase shape, count the cubes in each stack (how tall it is) and add the stacks; the cubes under the top ones are there even though you cannot see them.
Example
How many unit cubes make this solid? Give the volume in cubic units.
