Answer: Height of the block of southern pine is 7 cm.
Step-by-step explanation:
Since we have given that
Mass = 54.6 g
Density = 0.65 g/cm³
First we calculate the "Volume ":
[tex]Density=\dfrac{Mass}{volume}\\\\0.65=\dfrac{54.6}{Volume}\\\\\dfrac{54.6}{0.65}=Volume\\\\Volume=84\ cm^3[/tex]
Length of rectangular prism = 4 cm
Width of rectangular prism = 3 cm
Height of rectangular prism be 'h'.
So, Volume of rectangular prism = Length×Width×Height
[tex]84=4\times 3\times h\\\\84=12\times h\\\\\dfrac{84}{12}=h\\\\7=h[/tex]
Hence, height of the block of southern pine is 7 cm.
