This guy is selling me this tank and tells me it holds almost 3 gallons of water....

Bull-****! I love math. He gave me the area which is 10 x 6.25 x 3 in inches



I need to find the volume in cubic inches within this coolant tank.

So it would be multiplying length x width x height to get the volume

So the volume is:

10 x 6.25 x 3 = 187.5 in3

Then half it cause two right angle triangles make a square (thanks to tomaso12)

And you get…93.75 in3

One gallon holds 231 in3

3 gallons? What a turd!!

actually it would be

area of triangle (6.25" x 3")/2 = 9.375

multiplied by the length of the prism, so 9.372 x 10" = 93.75 cubes

still not 3 gallons :D

Thats only if the triangles are right angle isnt it?

Still, def not 3 gallons.

dont feel silly.....multiplication is both associative and commutative, so it doesnt matter where the "1/2" factor goes....so a*b*c*d is entirely equivalent to d*a*b*c :D

I thought the ultimate goal was to find the capacity in gallons in order to prove this shmuck wrong.

According to my handy converter, which agrees with the 231 cubic inches/gallon that you mentioned.

93.75 cubic inches = .4058 Gallon

Hardly 3 gallons, Hell it's not even half a gallon.
