Find the area of the cross section times by height
Explanation:
High and low tides are caused by the Moon.
The Moon's gravitational pull induces something called the tidal force.
The tidal force causes Earth—and its water—to bulge out on its nearest and furthest sides from the Moon.
The Moon is responsible for high and low tides.

The water causes the hardening of concrete through a process called hydration. Hydration is a chemical reaction in which the major compounds in cement form chemical bonds with water molecules and become hydrates or hydration products.
Considering this information, the answer is D.
