Ablock of southern pine wood has a mass of 54.6 g and density of 0.65 g/cm3 . the block is a rectangular prism with a length of 4 cm and a width of 3 cm.

what is the height of the block of southern pine?

Height = 7 cm

Step-by-step explanation:

A block of southern pine has a mass of 54.60 g and density of 0.65 g/cm³.

The block is a rectangular prism with a length of 4 cm and a width of 3 cm.

Now we know

It is given in the question that mass = 54.60 g

and volume = 54.60 = (length×width×height)

Therefore by putting these values in the question

0.65 = 54.60/ (Length×width×height) = 54.60/(4×3×h)

12h×(0.65) = 54.60

7.80h = 54.60

h = 54.60/7.80 = 7 cm

Answer is height = 7 cm.

$15 each

step-by-step explanation:

$45/3 children= $15 each

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
