Answer:
The volume of a triangular prism mentioned is:
- 210
Step-by-step explanation:
To obtain the volume of a triangular prism, first, you must identify the base area with the values given in the exercise:
- Base area = Base length * Base height.
- Base area = 6 * 5
- Base area = 30
When you have the base area, you can use the formula below to calculate the volume of the triangular prism:
- Volume of a triangular prism = Base area * Prism height.
- Volume of a triangular prism = 30 * 7
- <u>Volume of a triangular prism = 210 </u><u></u>
Answer: 50 red apples
Step-by-step explanation:
First divide 20 by 2 to know what you will multiply 5 by, so 20 divided by 2 equals 10. Now you multiply 5 by 10 to know how many red apples there are. 5 multiplied by 10 equals 50. So there are 20 tomatoes and 50 red apples.
