Ametal stands specifies a maximum load of 450 lb. will it support an aquarium that weighs 59.5 lb and is filled with 37.9 l of seawater (d = 1.03 g/ml)?

First calculate the corresponding mass of 37.9 L

M = 37.9 L ( 1000 ml / 1 L ) ( 1.03 g / ml)

M = 39,037 g

Convert g to pounds

M = 39,037 g ( 1 lb / 453.592 g)

M = 86.06 lb

Then add the 59.5 ln

M = 86.06 + 59.5 = 145.56 lb so it will support it
