Answer:
The surface area of the square prism is ![104\ cm^{2}](https://tex.z-dn.net/?f=104%5C%20cm%5E%7B2%7D)
Step-by-step explanation:
we know that
The surface area of the square prism is equal to
![SA=2b^{2} +4bh](https://tex.z-dn.net/?f=SA%3D2b%5E%7B2%7D%20%2B4bh)
where
b is the length side of the square base
h is the height of the prism
In this problem we have
![b=2\ cm](https://tex.z-dn.net/?f=b%3D2%5C%20cm)
![h=12\ cm](https://tex.z-dn.net/?f=h%3D12%5C%20cm)
substitute
![SA=2(2)^{2} +4(2)(12)=104\ cm^{2}](https://tex.z-dn.net/?f=SA%3D2%282%29%5E%7B2%7D%20%2B4%282%29%2812%29%3D104%5C%20cm%5E%7B2%7D)
Answer:
The 64 ounce jug of milk costs $0.010 more per ounce than the 128 ounce jug of milk/
Step-by-step explanation:
3.20/128=$0.025 per ounce jug of milk
2.24/64=$0.035 per ounce jug of milk
0.035 - 0.025 = .010

Answer:
3. 7
Step-by-step explanation:
The distance formula applies in 3 dimensions as well as 2.
d = √((x2 -x1)² +(y2 -y1)² +(z2 -z1)²)
d = √((-2)² +6² +3²) = √(4 +36 +9) = √49
d = 7
The distance between the two points is 7 units.
