Step 1
find the volume of the square box
volume=area of the base*height
area of the base=10²-----> 100 units²
height=4 units
volume square box=100*4----> 400 units³
step 2
volume rectangular box=2*volume square box
volume rectangular box=2*400------> 800 units³
volume rectangular box=L*W*H
H=5 units
W=10 units
Volume=800 units³
800=L*10*5------> solve for L
L=800/(10*5)------> L=16 units
the answer is
the length of the rectangular box is 16 units
Answer:
The answer is " 0.83"
Step-by-step explanation:
In the question some data is missing, that's value can be defined as follows:
Values:


Formula:


This is a tough one. What we are looking for is how long (how much time) was spent in the mountains. So we are looking for t, time. 3 hours 48 minutes is 3.8 hours. Both have to be in terms of one or the other, you cant have unknown mountain time and plain time, so let's say that mountain time is t. That means that plain time is 3.8-t. Multiply the rates times the times for each and add them together and set them equal to the total distance. 90(3.8-t)+37.5t=300. Solve for t. The time spent in the mountains was 48 minutes
The hemisphere is half the volume of a sphere. Since we are given the circumference, we can solve for the radius of the sphere. That is

Part A
We can now compute for the volume of the hemisphere.

Part B
We just need to convert the volume into its corresponding gallons
