Answer:

B. 12.5%

Step-by-step explanation:

Add all the hours together to get 20. We make the assumption that 20 is 100% since it is our output value. We next represent the value we seek with x. From step 1, it follows that 100%=20. In the same vein, x%=2.5.This gives us a pair of simple equations:

100%=20(1)

x%=2.5(2)

By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS (left hand side) of both equations have the same unit (%); we have

$\frac{100}{x}$ = $\frac{20}{2.5}$

Taking the inverse (or reciprocal) of both sides gives us this:

$\frac{x}{100} =\frac{2.5}{20}$

>> x=12.5\%

Therefore, 2.5 is 12.5% of 20.

You first work out the mean then for each number subtract the mean and square the result then work out the mean of those squared differences and take the square rot of that and you're done :)

We will determine the surface area as follows:

$A=6(5cm\ast5cm)\Rightarrow A=150cm^2$

So, the total surface area is 150 cm^2.
