To find the volume of each cuboid, we count how many small cubes fit inside it. Since each small cube is 1 unit³, multiplying length × width × height gives the total number of cubes — which equals the volume.
Let’s go step by step for each one:
---
Cuboid 1:
- Length = 4 units (count along the front)
- Width = 3 units (count going back)
- Height = 2 units (count up)
→ Volume = 4 × 3 × 2 =
24
Cuboid 2:
- Length = 5
- Width = 3
- Height = 3
→ Volume = 5 × 3 × 3 =
45
Cuboid 3:
- Length = 3
- Width = 2
- Height = 2
→ Volume = 3 × 2 × 2 =
12
Cuboid 4:
- Length = 4
- Width = 4
- Height = 3
→ Volume = 4 × 4 × 3 =
48
Cuboid 5:
- Length = 6
- Width = 4
- Height = 2
→ Volume = 6 × 4 × 2 =
48
Cuboid 6:
- Length = 5
- Width = 3
- Height = 3
→ Volume = 5 × 3 × 3 =
45
