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 ":
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
Hence, height of the block of southern pine is 7 cm.

Answer:
The Triangle Sum Theorem is also called the Triangle Angle Sum Theorem or Angle Sum Theorem. It says that all the angles <em>inside</em> a triangle add up to 180°.
---------------------------------------------------------------------------------
Take a look at the picture attached. It has a "formula": ∠a+∠b+∠c=180°
Use this as it will help you a lot. You plug in the info you already know (it doesn't matter which angle is a,b,c) and solve for the missing one. :)
