Suppose you hold a 12-cm3 block of aluminum and a 2.0-cm3 block of brass in your two hands. which block has more mass?

The density of aluminum is 2.7 so the mass would be the density times the volume. 12*2.7=32.4 g.

The density of brass is 8.4. 8.4*2=16.8 g.

The aluminum block has a greater mass.

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
