By dividing the corresponding sides of similar sides' lengths
Volume = are base*height
32 = x^2*h --> h = 32/x^2
surface area = 4x(32/x^2) + x^2
SA = 128/x + x^2
SA' = -128/x^2 + 2x = 0
2x = 128/x^2
2x^3 = 128
x^3 = 64
x = 4
surface area minimized when length of base is 4 in.
hope this help

Answer:
16.8 ft
Step-by-step explanation:
use pythagorean formula
, you are solving for the hypotenuse
x=16.8 ft
Rounding numbers or
compatible numbers are usually use to be able to calculate a certain
number easier and faster.
For the given equation, we have 302 + 412 which is equals to 714 not 577.
Now, let’s look for a rounding or compatible number to estimate the sum.
=> 302, we have 300 as rounding number or compatible numbers
=> 412, we can have 415 as rounding numbers
=> 300 + 415 = 715.
The exact answer is 714 and our estimated is 715.
