a water tank is 1.2 meter square and 1.35 meter deep. it is half full of water. how many times can a 9 liter bucket be filled from the tank?

Answer 1

First, we need to calculate the volume of the water tank:

Volume = length x width x depth
Volume = 1.2m x 1.2m x 1.35m
Volume = 1.62 cubic meters

Since the tank is half full, the volume of water in the tank is:
1.62 cubic meters / 2 = 0.81 cubic meters

To convert the volume to liters, we multiply by 1000 (1 cubic meter = 1000 liters):
0.81 cubic meters x 1000 = 810 liters

Now we can calculate how many times a 9 liter bucket can be filled from the tank:
810 liters / 9 liters = 90

So, a 9 liter bucket can be filled 90 times from the tank.
