Answer:
1. 672 in.³
2. She still has 12 balloons.
3. 124 degrees
4. 600
5. She has $28 left.
Explanation:
1.
The volume of a rectangular prism is
length × width × height
The length × width of the bas is also the area of the base.
The volume of a prism is also
area of base × height
Here you are given the area of the base as 56 in.²
The height is 12 in.
All you need to do is use the second formula:
volume = area of base × height
volume = 56 in.² × 12 in.
volume = 672 in.³
2.
She had 16 balloons.
1/4 of the 16 balloons blew away.
1/4 of 16 = 1/4 × 16 = 1/4 × 16/1 = 16/4 = 4
4 balloons blew away.
She started with 16. 4 blew away. We need to subtract.
16 balloons - 4 balloons = 12 balloons
Answer: She still has 12 balloons.
3.
The boiling point of water is 212 degrees Fahrenheit.
The pot is at 88 degrees Fahrenheit.
The temperature needs to go from 88 degrees up to 212 degrees.
We need to find the difference between 212 and 88.
We use subtraction.
212 - 88 = 124
Answer: 124 degrees
4.
8268 is approximately 8300.
8875 is approximately 8900.
The difference is 8900 - 8300 = 600
Answer: 600
5.
She started with: $100
She spent: $26, $8, $38
The total she spent is: $26 + $8 + $38 = $72
She had $100 and spent $72. She has the difference.
We need to subtract.
$100 - $72 = $28
Answer: She has $28 left.
