What is the value of the ratio of the surface area to the volume of the right prism?

a.
1.9

b.
1.05

c.
0.9

d.
0.53

The correct answer for the question that is being presented above is this one: "A. 1.9"

We can get the surface area of the rectangular prism by using this formula
A = 2 ( w l + h l + h w ) 
Given that the 
l = 5
w = 4
h =2

Then, the surface area is
A = 2 ( w l + h l + h w ) 
A = 2 (4*5 + 2*5 + 2*4)
A = 2 (20 + 10 + 8)
A = 2 (38)
A = 76 m^2

In order to get the volume, we have to use this formula.
Volume = l * w * h
Volume = 5 * 4 * 2
Volume = 40m^3

the value of the ratio of the surface area to the volume of the right prism
76:40 = 19:10 =  1.9

The percent increase is 25%
