formula for area of parallelogram
= A=bh
Answer: s= - 8/5
Step-by-step explanation:
Simplify 4-164−16 to -12−12.
-12=2+5(s+14)
−12=2+5(s+14)
2 Subtract 22 from both sides.
-12-2=5(s+14)
−12−2=5(s+14)
3 Simplify -12-2−12−2 to -14−14.
-14=5(s+14)
−14=5(s+14)
Let x be the height of the box and y be the length of one side of the base then:-
V = xy^2 = 108
x = 108/y^2
Surface area = y^2 + 4xy
S = y^2 + 4y* 108/y^2
S = y^2 + 432/y
Finding the derivative:-
dS/dy = 2y - 432/y^2 = 0
2y^3 = 432
y^3 = 216
y = 6
Check if this gives a minimum value:-
second derivative = 2 + 864/y^3 which is positive so minimum.
V = xy^2 = 108
36y = 108
y = 3
Answer :- dimensions of the box is 3*6*6 metres
