A rectangular tank whose dimensions are 8m by 7m by 5m contains water up to depth of 2m. How much more water can it hold

To determine how much more water the tank can hold, we need to calculate the volume of the tank and subtract the volume of water already in it.

The volume of a rectangular tank can be calculated by multiplying its length, width, and height. In this case, the tank's dimensions are given as 8m by 7m by 5m.

Volume of the tank = length x width x height
Volume of the tank = 8m x 7m x 5m
Volume of the tank = 280 m^3

The tank is already filled with water up to a depth of 2m. To calculate the volume of water already in the tank, we multiply the area of the base of the tank by the depth of the water.

The area of the base of the tank can be calculated by multiplying its length and width.

Area of the base of the tank = length x width
Area of the base of the tank = 8m x 7m
Area of the base of the tank = 56 m^2

Volume of water already in the tank = area of the base x depth of the water
Volume of water already in the tank = 56 m^2 x 2m
Volume of water already in the tank = 112 m^3

Now, to find out how much more water the tank can hold, we subtract the volume of water already in it from the total volume of the tank.

Remaining volume the tank can hold = Volume of the tank - Volume of water already in the tank
Remaining volume the tank can hold = 280 m^3 - 112 m^3
Remaining volume the tank can hold = 168 m^3

Therefore, the tank can hold an additional 168 cubic meters of water.

assuming the height is 5m, then it can hold another 3m of depth.

That is, a volume of 8*7*3 m^3
