Rectangular kitchen sink of Mohit can hold 4800 cubic inches
Solution:
Given that Mohit is trying to determine how much cubic water can fit in his rectangular kitchen sink.
The square base of sink has a side length of 20 inches.
Depth of the sink is 1 foot.
Need to determine how much cubic water can sink hold.
To determine how much cubic water can sink hold , we need to determine volume of sink
Volume of sink = area of square base x depth of the sink
Area of square base =

Where "a" is the length of side
Here a = 20 inches
As side length of square base is in inches and dept is in foot , we need to convert foot into inches so that all the units of measurement are same.
As 1 foot = 12 inches,
=> depth of the sink = 12 inches
=Volume of sink = 20 x 20 x 12 cubic inches
=> Volume of sink = 4800 cubic inches
Hence rectangular kitchen sink of Mohit can hold 4800 cubic inches.
