Answer: B
Step-by-step explanation:
Answer: 2x√5
Step-by-step explanation:
V = kl where k is the constant of proportionality
V = 24l = 24*30 = 720 in^3
720 = 30*h*w
hw = 720 / 30 = 24
also 2h + 2w = 20
w + h = 10
24/h + h = 10
24 + h^2 = 10h
h^2 - 10h + 24 = 0
(h - 4)(h - 6)=0
h = 4 inches or 6 inches.
