Quizizz worksheet on finding the volume of rectangular prisms using unit cubes.

Let's solve each of the first three questions step by step, based on the images and descriptions provided.

Question 1:

What is the volume of this rectangular prism?

The image shows a rectangular prism made up of small cubes. Let's determine its dimensions:

- Length: 4 cubes (along the front row)
- Width: 3 cubes (depth)
- Height: 2 cubes (vertical layers)

Now, calculate the volume:

$$
\text{Volume} = \text{Length} \times \text{Width} \times \text{Height} = 4 \times 3 \times 2 = 24 \text{ cubic units}
$$

> ✔ The correct answer is C: 24 cubic units

> ✘ Note: "Square units" is incorrect because volume is measured in cubic units, not square units.

Question 2:

What is the volume of this rectangular prism?

This is a cube-like structure with:
- Length: 3 cubes
- Width: 3 cubes
- Height: 3 cubes

$$
\text{Volume} = 3 \times 3 \times 3 = 27 \text{ cubic units}
$$

> ✔ The correct answer is B: 27 cubic units

Question 3:

The dimensions of this rectangular prism are:

Same as Question 2 — it’s a 3×3×3 cube.

So:
- Length = 3 cubes
- Width = 3 cubes
- Height = 3 cubes

> ✔ The correct answer is C: Length: 3 cubes, Width: 3 cubes, Height: 3 cubes

Note: Option D says height is 6 cubes, which would make it taller — but clearly, it's only 3 layers high.

✔ Final Answers:

1. C – 24 cubic units
2. B – 27 cubic units
3. C – Length: 3 cubes, Width: 3 cubes, Height: 3 cubes
