Question

1. A cube-shaped aquarium has edges that are 4 ft. long. The aquarium is filled with water that has a density of
51 lb/ft*3
(a) Should the aquarium be placed on a table that can support a maximum weight of 200 lb? Explain why or why not.
(b) Would the density of the water change if the aquarium was only half full? Explain.

Answer 1

so first you find the volume of the cube which is 4x4x4 or 64 
(a) is asking what the cube ways with water so you multiply 51  and 64= 3264 so the table would break so, no
(b) the equation 51 lb per cubic feet is the density so would filling it half way change the equation? also no
