Answer:
First, you have to find out the surface area of the box
=> Sbox = 10 x 5 x 2 + 10 x 8 x 2 + 5 x 8 x 2 = 340
Denote Surface area of the ball as Sball, we have:
Sball + Sbox = 352.56
=> Sball = 352.56 - Sbox = 352.56 - 340 = 12.56
From the formula to calculate Sball, we have:
4 x pi x radius^2 = 12.56
=> radius^2 = 12.56/(4 x pi) = 1 (here, pi = 3.14)
=> radius = 1 in
Hope this helps!

Answer: 136 m
Step-by-step explanation:
For first interval,
Time = 2 hours 40 minutes = ![2+\dfrac{40}{60}\text{ hours}\ [\text{1 hour = 60 minutes}]](https://tex.z-dn.net/?f=2%2B%5Cdfrac%7B40%7D%7B60%7D%5Ctext%7B%20hours%7D%5C%20%5B%5Ctext%7B1%20hour%20%3D%2060%20minutes%7D%5D)
Speed = 18 m/h
Distance = 
[Formula : Distance=Speed x time]
For second interval,
Time = 1 hour 50 minutes = ![1+\dfrac{50}{60}\text{ hours}\ [\text{1 hour = 60 minutes}]](https://tex.z-dn.net/?f=1%2B%5Cdfrac%7B50%7D%7B60%7D%5Ctext%7B%20hours%7D%5C%20%5B%5Ctext%7B1%20hour%20%3D%2060%20minutes%7D%5D)
Speed = 24 m/h
Distance = 
Total distance = 48 m +88 m = 136 m
Hence, he went 136 m.
Answer:
400 feet.
Explanation:
We need to find the difference between the lowest point of Galilee and the lowest point of Death Valley. We can find this by subtracting the lowest point of Galilee by the lowest point of Death Valley. It says the lowest point of Galilee is 682 feet below sea level and the lowest point of Death Valley is 282 feet below sea level. Therefore, we subtract 682 - 282, which equals 400.
