<h2><u>Q</u><u>u</u><u>e</u><u>s</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>
If a density of a wood is 0.5g/cm³, What is the mass of 2cm³ ?
<h2><u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u>:-</h2>
Density (D) of wood is = 0.5 g/cm³
Volume (V) of wood is = 2cm³
Mass (M) of wood is = ?
Now,
We know,
D = 
So,
M = D × V
M = 0.5 g/cm³ × 2cm³
M = 1 g
<h3>The mass of 2cm³ is <u>1</u><u>g</u>. [Answer]</h3>
<span>The answer is post and lintel. This is used on on windows, weight bearing supports trusses, over doors. This kind of construction is used to carry large heavy weight bearing loads of downward force. This is common in home basements where there are long beams and supporting posts beneath.</span>
