Acubic piece of metal measures 2.50 cm on each edge. if the metal is nickel, whose density is 8.90 g/cm3, what is the mass of the cube?

express your answer using three significant figures.

Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.

hope this helps.

have a great day!!
