Answer:
The volume is 1,050 cm³.
Step-by-step explanation:
This is because the formula for volume is: LxWxH
We have to multiply all of these so,
5 x 5 x 3 x 14 = 1,050
So the answer is 1,050 cm³.
Given :
Area of rectangle.
To Find :
The dimensions of a rectangle (in m) with area 1,728 m2 whose perimeter is as small as possible.
Solution :
Let, the dimensions of rectangle is x and y.
Area, A = xy.
x = A/y. ....1)
Perimeter, P = 2( x + y )
Putting value of x in above equation, we get :
For minimum P,
SO, it is a square.
Therefore, the dimensions are .24\sqrt{3}
Hence, this is the required solution.
