What is the volume of this prism?
Understand the Problem
The question asks us to calculate the volume of a rectangular prism. We are given the length, width, and height of the prism as 9m, 2m, and 5m respectively. To find the volume, we need to multiply these three dimensions together.
Answer
$90 \text{ m}^3$
Answer for screen readers
The volume of the prism is $90 \text{ m}^3$.
Steps to Solve
- Identify the given dimensions
The length is 9 m, the width is 2 m, and the height is 5 m.
- Calculate the volume
The volume $V$ of a rectangular prism is given by the formula: $V = \text{length} \times \text{width} \times \text{height}$.
Substitute the given values: $V = 9 \text{ m} \times 2 \text{ m} \times 5 \text{ m}$.
- Perform the multiplication
Multiply the numbers together: $V = 9 \times 2 \times 5 = 18 \times 5 = 90$.
Thus, the volume $V = 90 \text{ m}^3$.
The volume of the prism is $90 \text{ m}^3$.
More Information
The volume of a prism is the amount of space it occupies.
Tips
A common mistake is to add the dimensions instead of multiplying them. Remember that volume is a multiplicative property in this case, as it measures 3-dimensional space. Also, forgetting the units or using the wrong units (e.g., square meters instead of cubic meters) is a common mistake.
