An open concrete tank is internally 1m wide,2m long and1.5m deep the concrete being 10cm thick calculate the capacity of the tank in litres and the volume of the concrete

capacity (in dm^3) is 10*20*15 = 3000 dm^3 = 3000L

concrete (in cm^3) is 120*220*160 = 4,224,000 cm^3

Not correct

To calculate the capacity of the tank in liters, you need to determine the volume of water the tank can hold. In this case, the tank is internally 1m wide, 2m long, and 1.5m deep.

To find the volume, you can multiply these dimensions together: 1m x 2m x 1.5m = 3 cubic meters.

To convert cubic meters to liters, you can multiply by 1000 (since 1 cubic meter is equal to 1000 liters): 3 cubic meters x 1000 = 3000 liters.

Therefore, the capacity of the tank is 3000 liters.

Now, let's calculate the volume of the concrete.

The concrete thickness is given as 10cm, which is equal to 0.1 meters.

To find the internal dimensions of the tank (excluding the concrete), we can subtract twice the concrete thickness from the original dimensions:
Width: 1m - 2*(0.1m) = 0.8m
Length: 2m - 2*(0.1m) = 1.8m
Depth: 1.5m - 2*(0.1m) = 1.3m

Now, we can calculate the volume of the concrete by multiplying these internal dimensions:
Volume = 0.8m x 1.8m x 1.3m = 1.872 cubic meters.

Therefore, the volume of the concrete is 1.872 cubic meters.
