Answer:
area of square =length × length ×height
=6×6×8
=288
Subtract to find the difference in calories:
150-78 = 72
divide the difference by 150:
72/150 = 0.48
Multiply by 100 to get the percent:
0.48 x 100 = 48%

Answer:

Step-by-step explanation:
Let
Side of square base=x
Height of rectangular box=y
Area of square base=Area of top=
Area of one side face=
Cost of bottom=$9 per square ft
Cost of top=$5 square ft
Cost of sides=$4 per square ft
Total cost=$204
Volume of rectangular box=
Total cost=



Substitute the values of y

Differentiate w.r.t x







It takes positive because side length cannot be negative.
Again differentiate w.r. t x

Substitute the value

Hence, the volume of box is maximum at x=2.2 ft
Substitute the value of x

Greatest volume of box=
