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.

55? i think maybe

step-by-step explanation:

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
