Answer: D, 540
Step-by-step explanation:
The volume is h x l x w so it's 9x15x4
Answer:
63.63 in
Step-by-step explanation:
Pythagorean Theorem:
a² + b² = c²
Applying Pythagorean Theorem:
a = 22, b = 15, c = ?
22² + 15² = c²
c² = 484 + 225
c² = 709
c = √709
Perimeter = 22 + 15 + √709 = 63.63 in (nearest hundredth)
