Step-by-step solution

To calculate the volume of the cuboid, we apply the formula for the volume of a cuboid:

V=length×width×height V = \text{length} \times \text{width} \times \text{height}

Given:

  • Length = 9 cm
  • Width = 4 cm
  • Height = 5 cm

Now, substituting the values into the formula:

V=9×4×5 V = 9 \times 4 \times 5

First, multiply 9 and 4:

9×4=36 9 \times 4 = 36

Then, multiply the result by 5:

36×5=180 36 \times 5 = 180

Therefore, the volume of the cuboid is 180 cm³.

Since this is a multiple-choice question, the correct choice is 4: 180 cm3 \text{180 cm}^3 .

Final Answer

180 cm³

Key Points to Remember

Essential concepts to master this topic
  • Formula: Volume equals length times width times height
  • Technique: Multiply systematically: 9 × 4 = 36, then 36 × 5 = 180
  • Check: Units are cubic (cm³) and answer makes sense for given dimensions ✓

Common Mistakes

Avoid these frequent errors
  • Adding dimensions instead of multiplying
    Don't add 9 + 4 + 5 = 18 cm³! This gives perimeter thinking, not volume. Volume measures space inside, which grows in all three directions. Always multiply all three dimensions: length × width × height.

FAQ

Everything you need to know about this question

Why do we multiply the three dimensions?

+

Volume measures the space inside a 3D shape. When you extend in length, width, AND height simultaneously, you're filling a 3D space. Each dimension multiplies the others to create cubic units!

What's the difference between a cube and a cuboid?

+

A cube has all sides equal (like 5×5×5), while a cuboid (also called rectangular prism) can have different dimensions like our 9×4×5 example. Both use the same volume formula!

Why is the answer in cm³ and not just cm?

+

Volume uses cubic units because we're measuring 3D space. Think of it as counting little cubes: each 1cm × 1cm × 1cm cube = 1 cm³. Our shape contains 180 of these unit cubes!

Does the order of multiplication matter?

+

No! You can multiply length × width × height in any order: 9×4×5, or 5×9×4, or 4×5×9. All give the same answer: 180 cm³.

How can I visualize this volume?

+

Imagine stacking layers: Start with a 9×4 rectangle (36 squares), then stack 5 identical layers on top. You get 36×5 = 180 unit cubes total!

What if I get the wrong multiple choice answer?

+

Double-check your multiplication! Common errors: 9×4×5 ≠ 90 (forgot one dimension) or ≠ 35 (added instead of multiplied). Always multiply all three numbers.
