New cards
23
volume units
centimeters^2, meters^2, inches^2
New cards
24
Density units
g/mL, g/mL^3
New cards
25
volume
the amount that it takes to fill and object, or the amount of material that it can hold
New cards
26
Composite figures
made up of one or more shapes. to find the volume of the figure, find the volume of each shape alone, then add or subtract the volumes
New cards
27
Surface area
the total amount of material it takes to cover or wrap the shape. add the area of each side of the shape
New cards
28
Density
the ratio of mass and volume of an object. density refers to the relationship between mass and volume.
New cards
29
volume
the space an object takes up
New cards
30
mass
the weight of an object
New cards
31
pythagorean theorem
A^2+B^2=C^2
New cards
32
pythagorean theorem steps
find A^2, Find B^2, Add them together, you should have ANSWER= C^2, square root your answer to get the missing side of the triangle
New cards
33
cross section
a surface or shape that is exposed by making a cut through something. (think of a cross section as a thin slice of an object, whatever shape it is is your cross section)
New cards
34
rotations to form a 3-d shape
rotate a 2-d object around a line to make a 3-d shape. (hint: there can only be three possible shapes. Cylinder, Cone, or a Circle)(think about a coin- 2-d shape= circle, 3-d shape= sphere)
New cards
35
population area
population is the mass, the area in square miles is the volume. density have units of # of people/mi^2
