A plastic block has sides that measure 4 centimeters, 2 centimeters, and 3 centimeters. Its mass is 19.2 grams. Predict whether the block will float in water. Will it float in olive oil?

Is this supposed to be a regular box (straight sides, no triangular etc).
Volume = 4 cm x 2 cm x 3 cm = 24 cc.
density = mass/volume = 19.2/24 = ?? If the density is less than that of water, it will float. Same in olive oil. You must look up the densities of water and olive oil. 
Yes

4cm times 2cm times 3cm=24cc density = mass/ volume = 19.2 divied by 24 is 0.8 or .8

4 times 2 times 3 equals 24. 5 divided by 110 = 20 I just took of the zero and did 5 till I got to 11 which is 2 and then I added the 0 back

Info: 4 cm = 1 side, 3 cm = 1 side, 2 cm = 1 side, mass = 19.2 grams. As long as you know how to convert mass to density, the density of water, and the density of olive oil, this would have been a lot easier, but the densities of water and olive oil seen't listed. Density = Mass divided by volume. Error. Volume not listed. Loading... Length x Width x Height... Calculating... Volume = 24. Density = Mass divided by Volume... Calculating... Density = 00.8 Loading water Density... Water density = 0 g Loading Olive Oil Density... Olive Oil Density = 800  920... Answer = Yes in Water, Yes in Olive Oil.

Dont listen to my name.

even my name
