We know that

[the surface area]=2*[area of the base]+[perimeter of the base]*height
[the surface area]=2*[8*2.5]+[2*(8+2.5)]*12
[the surface area]=40+252-----> 292 in²

the answer is
<span>the least amount of cardboard needed to make the cereal box is 292 in</span>²

What is the value of x?
Dmitriy789 [7]
You have to start with the left triangle and find the side lengths. Since it is a 45-45-90, both sides are the same. Rule for this is hyp= sqrt2 * leg
Since hyp = 6sqrt2, the leg is 6.
The leg is also the hypotenuse of the triangle on the right side.
x is the side across from the hypotenuse and it is the short leg so x = (1/2)6
x = 3

if 5.25 MB have been downloaded and 2.25 MB are left. what percent of the application has already been downloaded?
ollegr [7]
5.25 + 2.25 = 7.50 MB

x/100 x (7.50) = 5.25
7.50x/100 = 5.25
7.50x = 5.25(100)
7.50x = 525
x = 525/7.50
x = 70
Hence, 70% of the application has already been downloaded.
