Engineering clubs often compete in the "concrete canoe" competition. Each club creates a canoe out of concrete and then the clubs race those canoes to find out whose design is best.

0.136 m^3

What is the weight, in Newtons, of an object with a volume of 2L and a density of 0.3kg/L?
V x P = m
m x g = weight
2L x 0.3kg/L = 0.6kg
0.6kg x 9.8m/s^2 = 5.88N
