A solid right pyramid has a regular hexagonal base with an area of 7.4 units2. The pyramid has a height of 6 units.

Lelechka [254]

Answer: Second option.

Step-by-step explanation:

You need to use the following formula:

$V=\frac{1}{3}Bh$

Where "B" is the area of its base and "h" is the height.

According to the data given in the exercise, you know that:

$B=7.4 units^2\\\\h=6\ units$

Therefore, knowing this values, you can substitute them into the formula shown before and then evaluate, in order to calculate the volume of thi right pyramid whose base is a regular hexagon.

Then, you get:

$V=\frac{1}{3}(7.4 units^2)(6\ units)\\\\V=14.8\ units^3$
