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
Answer: I think 70 percent
Step-by-step explanation:
It would be the one where measurement 1m is the side of the triangle, measurement 0.75m is the bottom of the triangle, and measurement 2m is the long side of the rectangle
V = 4/3 * pi * r^3
V = 4/3 * pi * 8.4^3
Simplify exponent:
V = 4/3 * pi * 592.704
Multiply:
