Cube

Six cubes fit on one edge, five fit along another, after 7 horizontal layers had been stacked on the box there is a space on top.

Space half length of edge of a unit cube- 6x5x7.5= cm3

space .47 length- 6x5x7.47

Sand Lab

V of sand alone= sand and water- sand

air space= dry sand-sand alone


Volume notes

unit of measurement- cm3

volume- LxWxH

Stand unit of length= meter

unit cube- 1 small cube, 1 cm on ech side

liquid unit of measurement- ml/cm3

1ml=1cm3

Lab Safety

nurse extension- 2828

acid must be added to water

never add water to acid

-could cause an exothermic reaction (reaction with heat or water)

-water is less dense than acid so it will sit on top of acid and could splash out

do not look down into a test tube/beaker while it is being heated

Sensitivity of balance

0.02g
