If one cubic centimeter of lead of lead has a mass of 11.3 what is the density?

Description : If one cubic centimeter of lead of lead has a mass of 11.3 what is the density?

Last Answer : Density is mass divided by volume. Think of it as how much mass there is in a given volume. Usually this is in units of grams divided by centimeters cubed (g/cm3). Assuming your mass of 11.3 is in grams you would just: ... V (volume) = ρ (density) (11.3 g) (1 cm3) = 11.3 g/cm3Hope this helped!

Is the scale for a scale drawing is 8 millimeters 1 centimeter. which is larger the actual object or the scale drawing?

Description : Is the scale for a scale drawing is 8 millimeters 1 centimeter. which is larger the actual object or the scale drawing?

Last Answer : To simplify a scale, convert to the same units, drop the unitsand divide by their highest common factor:1 cm = 10 mmdrawing : object = 8 mm : 1 cm→ 8 mm : 1 × 10 mm→ 8 mm : 10 mm→ 8 : 10→ 4 : 5→ object is larger than scale drawing.
