Answer:
b = 4.6 ft
h = 2.3 ft
Step-by-step explanation:
The volume of the tank is given by:

Where 'b' is the length of the each side of the square base, and 'h' is the height of the tank.
The surface area can be written as:

The value of b for which the derivate of the expression above is zero is the value that yields the minimum surface area:

The value of h is then:

Rounded to the nearest tenth, the dimensions are b = 4.6 ft and h = 2.3 ft.
Answer: C
Step-by-step explanation:
27 x .20 = 5.40
Closest answer, should be 5.40 though.
the center of gravity of all triangles is at the intersection of the three midlines.
2) The area of the three boy gogle fermed by the line from the center of gravity of the triangle to each verten is equal, which is 1/3 of the area of the origiend briangle. 6o we can see that selecting option. 60 C is shown in figura.
the answer is c
