Answer:
Length of the sides of the base (x) = 7.606 ft
Height (h) = 3.802 ft
The minimum surface area is 173.55 ft²
Step-by-step explanation:
Surface area is given by:
The value of x for which the derivate of the surface area function is zero, is the length of the sides of the base that minimizes surface area:
The height of the box is given by:
The dimensions of the box with minimum surface area are:
Length of the sides of the base (x) = 7.606 ft
Height (h) = 3.802 ft
The absolute minimum is:
The minimum surface area is 173.55 ft²

Answer:
Step-by-step explanation:
If all were ducks, there would be 28·2 = 56 legs. There are 94-56 = 38 more than that. Each cow that replaces a duck adds 2 legs, so there must be 38/2 = 19 such replacements, hence 19 cows. The remaining 28-19 = 9 animals are ducks.
There are 19 cows and 9 ducks.
