To find the volume of a prism, you typically use the formula:
\[ \text{Volume} = \text{Base Area} \times \text{Height} \]
From your calculations, it looks like you're working with a rectangular prism where the dimensions are given (though it's not entirely clear what each number represents). Let's break down the numbers you provided:
-
Base Area Calculation:
- The base dimensions you mentioned seem to be 5 cm and 12 cm, so you calculated the area of the base as: \[ 5 \times 12 = 60 , \text{cm}^2 \]
- This is correct for the base area.
-
Volume Calculation:
- If the height of the prism is 6 cm, then the volume of the prism would be: \[ \text{Volume} = \text{Base Area} \times \text{Height} = 60 , \text{cm}^2 \times 6 , \text{cm} = 360 , \text{cm}^3 \]
- This aligns with your calculation of \(5 \times 12 \times 6 = 360 , \text{cm}^3\).
-
Other Calculations:
- The first line \(5 + 12 + 6 = 23 \) does not relate to volume, as volume involves multiplication, not addition.
- The calculation \( (5 \times 12) \times 12 = 720 , \text{cm}^3\) is also incorrect in the context of a standard prism volume; it seems to double one of the dimensions.
Conclusion:
- The volume of the rectangular prism, using the base dimensions of 5 cm by 12 cm and height of 6 cm, is 360 cm³.
- The proper formula to remember is: \[ \text{Volume} = \text{Base Length} \times \text{Base Width} \times \text{Height} \] where for this prism, it would be \(5 \times 12 \times 6\).
