What is the surface area of the rectangle prism

Mathematics
1 answer:
AnnyKZ [126]3 years ago
7 0

Answer:

310 in²

Step-by-step explanation:

The general formula for the surface area of a prism is:

SA = 2ab + 2ac + 2bc, where 'a', 'b' and 'c' are the measures of the sides.  In this case the lengths are 4 in, 5 in and 15 in.

a = 4 in

b = 5 in

c = 15 in

SA = 2(4*5) + 2(4*15) + 2(5*15)

SA = 40 + 120 + 150 = 310 in²

After sailing 12 mi, a sailor changed direction and increased the boat's speed by 4 mph. an additional 18 mi was sailed at the i
inessss [21]
Let the speed for the first 12 mi be x mi/h, the speed for 18 mi was (x+4) mi/h
thus given that
time=distance/speed 
the average time will be:
3=(12+18)/(x+x+4)
3=30/(2x+4)
solving for x we get
3(2x+4)=30
6x+6=30
6x=24
x=4 mi/hr
Answer: 12 mi/hr
