How to calculate volume of a prism
To determine which set of dimensions represents a right rectangular prism with a different volume than the others, calculate the volume for each set of dimensions and compare them.
The volume of a right rectangular prism is given by the formula: V = length * width * height.
Let's calculate the volumes for each set of dimensions:
For the dimensions: length: 1/2; width: 10; height:
![3 \frac {1}2](https://img.qammunity.org/2021/formulas/mathematics/high-school/gu2p6p09a840etr9gs9fc0c6nufo6vmlqh.png)
V₁ = (1/2) * 10 * (7/2) = 35/2 = 17.5
For the dimensions: length: 1; width: 5; height: 7
V₂ = 1 * 5 * 7 = 35
For the dimensions: length: 2; width: 5; height:
![3 \frac {1}2](https://img.qammunity.org/2021/formulas/mathematics/high-school/gu2p6p09a840etr9gs9fc0c6nufo6vmlqh.png)
V₃ = 2 * 5 * (7/2) = 35
For the dimensions: length: 4; width:
; height:
![3 \frac {1}2](https://img.qammunity.org/2021/formulas/mathematics/high-school/gu2p6p09a840etr9gs9fc0c6nufo6vmlqh.png)
V₄ = 4 * (5/2) * (7/2) = 35
Comparing the volumes, we can see that:
V₁ = 17.5
V₂ = V₃ = V₄ = 35
Therefore, the set of dimensions that has a different volume than the others is:
length: 1/2; width: 10; height:
