The optimum shape of such a box is half a cube. The corresponding cube will have a volume of 2×256 ft³ = 512 ft³ = (8 ft)³. Such a box has a square base that is 8 ft on a side. If the height is half that of the cube, it will be 4 ft.
The dimensions of your box will be 8 ft square by 4 ft high.
_____
If the base dimension is x ft, the area (quantity of material) is
... a = x² + 4x(256/x²)
... a = x² + 1024x⁻¹
Then the derivative of area with respect to x is
... a' = 2x -1024x⁻²
Setting this derivative to zero and solving for x gives the value of x for minimum area.
... 0 = 2x -1024/x²
... 512 = x³
... x = 8 . . . . . . . . same as above.
• Use opposite operation to isolate x
28 ➗ 25 = 25x
• Write the value of x
X = 1.12
Put 10% into a fraction 10/100 = 1/10. Now times 88 KG by 1/10 and you should have the answer.
10% = 10/100 = 1/10
88/1 X 1/10 = 1/20
Answer:
-1/12
Step-by-step explanation:
change divide sign to multiply by reciprocating
