Calculate Cuboid Volume: Finding V = 8cm × 10cm × 9cm

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

• Step 1: Identify the given dimensions: length, width, and height.
• Step 2: Apply the volume formula for a cuboid.
• Step 3: Perform the multiplication to find the volume.
• Step 4: Match the result with the provided choices to confirm the correct answer.

Now, let's work through each step:
Step 1: We are given the cuboid's dimensions: length = 8 cm, width = 10 cm, height = 9 cm.
Step 2: To find the volume $V$ of the cuboid, we use the formula:
$V = \text{length} \times \text{width} \times \text{height}$.
Step 3: Substitute the given values into the formula:
$V = 8 \, \text{cm} \times 10 \, \text{cm} \times 9 \, \text{cm}$.
Calculate the product:
$V = 8 \times 10 \times 9 = 720 \, \text{cm}^3$.
Step 4: The calculated volume is $720 \, \text{cm}^3$, which matches choice 4.

Therefore, the solution to the problem is $720 \, \text{cm}^3$.
