In this worksheet, we will practice finding volumes of cuboids, then composite solids made of cuboids, and then prisms.

**Q3: **

How many cubes with a side length of does it take to fill the given prism?

**Q4: **

Work out the volume of the right triangular prism shown.

**Q6: **

Given that the volume of each small cube is 1 cubic unit, find the volume of this prism.

**Q7: **

Given that each cube has a side length of 1 unit, find the volume of the given prism.

- A60 cubic units
- B48.6 cubic units
- C63 cubic units
- D64.8 cubic units
- E66 cubic units
