50 + 20h = 100 + 10h
20h - 10h = 100 - 50
10h = 50
h = 50/10
h = 5 <== they will charge the same at 5 hrs
Answer:
Volume = 1596.2 cubic cm
Step-by-step explanation:
Volume = volume of box - volume of cylinder
Volume = (LxWxH) - 1/3 (pi * r^2 *h)
Volume = (10 x 12 x 20) -1/3 (3.14 x 8^2 x 12)
Volume = 2400 - 803.8
Volume = 1596.2 cm^3
