For a snow sculpture contest, snow is packed into a cube-shaped box with an edge length of
8 feet. The box is frozen and removed, leaving a cube of
snow. One cubic foot of the snow weighs about 30 pounds.
You can estimate the weight (in pounds) of the cube using
the expression 30V where Vis the volume (in cubic feet) of
the snow. About how much does the uncarved cube weigh?
