Question

250 men took a dip in a water tank at a time, which is 80 m $\times$ 50 m. What is the rise in the water level if the average displacement of 1 man is 4 m${}^3$?

• A. 22 cm
• B. 25 cm
• C. 18 cm
• D. 30 cm

Answer 1

Answer: (B)

25 cm

Length of water tank=80m
b=50m
Volume of water in water tank=Total volume of water displaced
lbh=80*50*h=4*250
$80\ast 50\ast h=1000$
$h=0.25m=25cm$
Answer (B) 25cm
