Answer:
6 ft, 6 ft, 12 ft
Step-by-step explanation:
Area = 216 sq feet
let the sides are y, y and z.
Area, A = 2y² + 2yz
216 = 2y² + 2yz
108 = y² + yz
z = (108 - y²) / y .... (1)
Volume, V = y²z
Substitute the values of z from equation (1)
V = 108 y - y³
Differentiate with respect to y
dV/dy = 108 - 3y²
Put it equal to zero for maxima and minima
3y² = 108
y = 6 ft
So, z = (108 - 36) / 6 = 12 ft
Thus, the sides are 6 ft, 6 ft, 12 ft.

5 1/2 * 1 2/5
They can be turned into improper fractions to make multiplying easier. Do this by multiplying the whole number by the denominator and then adding the numerator, and then putting that number over the given denominator.
11/2 * 7/5
The numerators are multiplied and the denominators are multiplied.
77/10
Now, reduce it back into a mixed number.
7 7/10
Hope this helps! :D
