The first thing we must do in this case is to calculate the surface area of the rectangular prism.
We have then:
A = 2 * ((L * h) + (L * w) + (h * w))
Where,
L: long
w: width
h: height
Substituting the values:
A = 2 * ((7.5 * 10) + (7.5 * 2) + (10 * 2))
A = 220
Then, "Manufacturing each box requires 10% more cardboard than the box's surface area"
Ar = 220 * 1.10
Ar = 242
242-220 = 22
Answer:
is needed 22 in ^ 2 cardboard to make each box
<h3><u>The function used to find the perimeter of a square, represented by y, given the length of a side, represented by x is: y = 4x</u></h3>
<em><u>Solution:</u></em>
Let "y" be the perimeter of square
Let the length of side be "x"
From given,
The perimeter of a square is the product of four and the length of a side
Which means,
Substituting the given variables,
Thus perimeter of square is y = 4x

Answer:
25.3 Miles is the shortest route between newport and kensington
Step-by-step explanation:
Answer:
p+5+7=p+12
p/(p+12) ×900=120
900p=120(p+12)
90p=12(p+12)
90p=12p+144
90p-12p=144
78p=144
p=144/78
