Answer:
Surface Area Formula for a Rectangular Prism: A = 2( wl + hl + hw)
w = width
l = length
h = height
In this picture, it shows that the height is 4, the width is 2, and the length is 3. Therefore, we have:
A = 2 [ (2*3) + (4*3) + (4*2) ]
A = 2(6 + 12 + 8)
A = 2(26)
A = 52
Thus, the surface area is 52 cm^2.
The distance could be calculated as follows:
d =
d =
d =

Answer:
Option 4: is the correct answer.
Step-by-step explanation:
The given fractions are mixed fractions. the mixed fractions have to be converted into proper fractions before performing any operation like addition, subtraction etc.
Given fractions are:
Converting into proper fractions
Making the denominator same
We have to multiply first fraction by 3 and second by 6
Converting into mixed fraction:
Hence,
Option 4: is the correct answer.
1hr=60mins
1min=60seconds
1hour=60*60=3600seconds
ratio and proportaion
distance/time=distance/time
39/7=x/3600
times both sides by (7*3600)
140400=7x
divide both sides by 7
20057 and 1/7=x
answer is 20057 and 1/7 meters per hour
or
20.0571428km per hour
