Answer:
1/25
Step-by-step explanation:
square has 4 sides, if you add them all up you get 4/5.
1/5+1/5+1/5+1/5=4/5
so each side is 1/5
Area=length * width
A=1/5*1/5=1/25
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

let x =the number
Step-by-step explanation:
81+x=3x-39

120=2x
120/2=2x/2
60=x
therefore x =60
