(a) What is the length of the edge in centimeters?

(b) What is the volume of the cube in cubic centimeters? (Remember, the lengths of all edges of a cube are equal.) Watch your significant figures. Use scientific notation if you have to.

(c) The cube has a mass of 111 kg. What is its density in grams per milliliter? Watch your significant figures.

**DrBob222**, Sunday, October 16, 2011 at 8:42pma)1 meter = 100 cm, so the length of the edge is 100 + 1.40 = 101.40 cm but watch the number of s.f..

b)volume = edge^3.

c)density = mass/volume
