Chapter 9 Volume, Density, And Displacement

Question 1

Volume of a cube

Answer 1

V= e^3 (e stands for edge)

Question 2

Volume of a rectangular prism

Answer 2

V=lwh

Question 3

Volume of a pyramid

Answer 3

V=1/3B(h) (B is the area of the base)

Question 4

Volume of a cone

Answer 4

V=1/3(Pi)r^2h

Question 5

Volume of a cylinder

Answer 5

V=(Pi)r^2h

Question 6

Volume of a sphere

Answer 6

V=4(Pi)r^3/3

Question 7

Volume of a hemisphere

Answer 7

V=2(Pi)r^3/3

Question 8

Volume

Answer 8

Volume equals the area of the base times the height of the prism.

Question 9

Density formula

Answer 9

D=mass/volume

Note: If the density is greater than one, it sinks. If the density is less than one, then it sinks.

Question 10

Displacement

Answer 10

Find the volume of an irregularly shaped object by measuring how much the water level increases once the object is full submerged. Find the volume of the prism created by that change.
