We will use the formula for finding the surface area of a rectangular prism.
Formula =
SA <span>= </span><span>2 </span><span>(</span><span>w</span><span>l</span><span>+</span><span>h</span><span>l</span><span>+</span><span>h</span><span>w</span><span>)</span>SA = 2 (8·14 + 4·14 + 4·8)
SA = 2 (112 + 56 + 32)
SA = 2 (200)
SA = 400
The gift box needs C) 400 in wrapping paper to wrap the gift box. <span />
Area= l * b
12= 5 * b
b = 12/ 5
b= 2.4 ft
To do this you need the mean.
(81*9+70)/10 that is the mean equation.
Solve.
(799)/10
79.9
79.9% Will be your grade or a C
The value of 
is 
Explanation:
Given that the functions 
and 
We need to determine the value of
The value of can be determined by substituting the value of 
and 
and simplifying the terms.
Thus, let us assign in the function , we have,
Now, let us assign in the function , we get,
Grouping the like terms, we have,
Adding the like terms, we get,
Hence, the value of is
Percent formula : is/of = %/100
% = n
is = 23
of = 94
now we just sub our numbers into the formula
23/94 = n/100 <===
