Answer: 225m^3
Step-by-step explanation:
Volume = Bh where "B" is the area of the base and "h" is the height
So, area of the base = 1/2(length)(height) = 1/2(5)(9) = 22.5 m^2.
Then multiply by the height.
22.5x10= 225m^3
Answer:
Step-by-step explanation:
density of oil, d = 30 lb/ft³
Volume of tank, V = l x w x h = 1 x 2 x 1 = 2 ft³
mass of oil, m = Volume x density of oil = 1 x 30 = 30 lb
Work = m x g x h = 30 x 32 x 3 = 2880 units
