The larger cube’s volume is about blank cm

Volume = mass divided by density.

You are given the mass and density for the smaller cube so you can calculate it's volume:

Volume = 20  / 7.87 = 2.541 cubic cm's.

Now you are told the larger cube has 2 times the volume:

Volume of larger cube = 2.541 x 2 = 5.08 cubic cm's.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
