Step-by-step solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify the given dimensions: length = 9 cm, width = 4 cm, height = 5 cm.
  • Step 2: Apply the formula for the volume of a cuboid, V=length×width×height V = \text{length} \times \text{width} \times \text{height} .
  • Step 3: Calculate the value by substituting the given dimensions into the formula.

Now, let's work through each step:

Step 1: Given dimensions are:
- Length = 9 cm
- Width = 4 cm
- Height = 5 cm

Step 2: Use the formula for the volume of a cuboid:
V=length×width×height V = \text{length} \times \text{width} \times \text{height}

Step 3: Substitute the values into the formula:
V=9cm×4cm×5cm V = 9 \, \text{cm} \times 4 \, \text{cm} \times 5 \, \text{cm}

Calculate the product:
V=180cm3 V = 180 \, \text{cm}^3

Therefore, the volume of the cuboid is 180cm3 180 \, \text{cm}^3 .

Final Answer

180 cm³

Key Points to Remember

Essential concepts to master this topic
  • Formula: Volume of cuboid equals length × width × height
  • Technique: Multiply dimensions in order: 9 × 4 × 5 = 180
  • Check: Verify units are cubed (cm³) and all dimensions used ✓

Common Mistakes

Avoid these frequent errors
  • Adding dimensions instead of multiplying
    Don't add 9 + 4 + 5 = 18 cm! This gives perimeter of one face, not volume. Volume measures space inside, requiring all three dimensions multiplied together. Always multiply length × width × height for volume.

FAQ

Everything you need to know about this question

Why do we multiply all three dimensions?

+

Volume measures the space inside a 3D shape. You need length × width to get the area of the base, then × height to 'stack up' that area through the entire height of the shape.

What's the difference between area and volume?

+

Area is 2D (measured in cm²) and uses two dimensions. Volume is 3D (measured in cm³) and uses three dimensions. Think of area as the floor space, volume as the room space.

Why is the answer in cm³ and not just cm?

+

The cubic units (cm³) show we're measuring volume! When you multiply cm × cm × cm, you get cm³. This tells you it's a 3-dimensional measurement.

Does the order of multiplication matter?

+

No! 9 × 4 × 5 gives the same result as 5 × 9 × 4 or any other order. Multiplication is commutative, so arrange the numbers however is easiest for you to calculate.

What if I forget one of the dimensions?

+

You'll get the wrong answer! Always check that you've used all three measurements: length, width, and height. Missing any dimension means you're not calculating true volume.

How can I make sure I don't make calculation errors?

+

Break it into steps: 9 × 4 = 36, then 36 × 5 = 180. You can also check by doing it a different way: 4 × 5 = 20, then 9 × 20 = 180.
