19. A rectangular block of wood measures 3cm
by 6 cm by 4 cm has a mass of 80.0 grams. What
is the density of the wood?
a. 5760 g/cm
b. 0.9 cm3/g
c. 1.11 g/cm3
d. 80 g/cm3

c. 1.11 g/cm³

Step-by-step explanation:

The formula for determining the volume of the rectangular block is expressed as

Volume = length × width × height

The rectangular block of wood measures 3cm by 6 cm by 4 cm. Therefore,

Volume = 3 × 6 × 4 = 72 cm³

The formula for determining density is expressed as

Density = mass/volume

Mass of wood = 80.0 grams

Volume of wood = 80/72 =

1.11 g/cm³

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
