An open concrete tank is internally 1m wide, 2m long and 1.5m deep, the concrete being 10cm thick. Calculate the capacity of the tank in liters and the volume of concrete used in m

Answer 1

To calculate the capacity of the tank in liters, we need to multiply the width, length, and depth of the interior of the tank:

Capacity = 1m x 2m x 1.5m = 3 cubic meters

We need to convert cubic meters to liters, which we can do by multiplying by 1000:

Capacity = 3 cubic meters x 1000 = 3000 liters

To calculate the volume of the concrete used in meters, we need to subtract the interior volume of the tank from the exterior volume of the tank. The exterior dimensions of the tank will be the interior dimensions plus twice the thickness of the concrete walls:

Exterior width = 1m + 0.2m + 0.2m = 1.4m
Exterior length = 2m + 0.2m + 0.2m = 2.4m
Exterior depth = 1.5m + 0.2m + 0.2m = 1.9m

Now we can calculate the exterior volume of the tank:

Exterior volume = 1.4m x 2.4m x 1.9m = 8.064 cubic meters

To calculate the volume of the concrete used, we simply subtract the interior volume from the exterior volume:

Concrete volume = 8.064 cubic meters - 3 cubic meters = 5.064 cubic meters

Therefore, the capacity of the tank is 3000 liters and the volume of concrete used is 5.064 cubic meters.
