A water tank has a dimension 3 m long, 1.8 m wide and 2.2 m
high. It has a capacity of:

The answer is 11.8 m

Step-by-step explanation:

Hey Mate,

the volume of a cuboid is = whlso the volume of it is the capacity of the tank

so 3 x 1.8 x 2.2 = 11.88 m is the answer

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:
