Two others way to measure the volume with the tank of water

Now you will fill the tank and measure the height of the water, and put the object in the tank and measure again,

One way you will calculate all the volumes and make the subtraction.

H1 x L x W - H2 x L x W

Height1 x lenght x width – Height2 x length x width

Other way you will do the subtraction of the heights and calculate the volume, so the subtraction of the heights you will multiply for the area (length x width).

(H1 - H2) x L x W

(Height1 - Height2) x lenght x width
