The density of aluminum is 2700kg/m^3
It depends on how, where, etcFollot the directions from the fish finderThere is probably a gasket or something that will seal the boat, and it will tell you how to seal it.
Use rubber washers at both sidesYou can use plumber's washers, and then rubber caulk the bottomAfter it's done and dry, pour water inside the boat and look to see if there are little bubblesIf you get bubbles, it's a leakOdds are, the fish finder kit has everything you need though.
No dont drill holes your man tkept think it was gave you the exact answer
When mounting it do not put it in the center line of the hull or it could make the propeller have cavitation Mount off to the side Us starboard or any form of it 5200 quick set only as aluminium has issue with holding sand well first then mount drill hole install tranducermount where no 1 can step on it
In this question, the equation for Density should be usedD m / V solve for massThis gives m DVStill, make sure that you have units that can be cancelled when you make the division between the density and volumeSo, (20 cm^3) (1 m/1000cm)^3 (20 cm^3) (1m^3/1x10^9 cm^3) 1/50000000 2x10^-8 m^3 (this is the same as saying 2.e^-8but you're not done hereThus, m 2700kg/m^3 / 2x10^-8 m^3 1.35 e^11 kg because the m^3 are canceled leaving you with kg which is the mass that you were looking forIf your calculator gives a 135000000000, then understand that this is the same as 1.35x10^11Hope it helps! Good luck
