If the base is square, and the perimeter is 14.5, that means that each side of the base is 14.5/4=3.625. Since we now know the length and the width, as well as the height which is 16.8, we plug into the formula $\frac{lwh}{3}$ . So, plug in the details $\frac{3.625*3.625*16.8}{3}$ Your answer will be 73.6 cm^3

The formula of pyramid:
$\frac{1}{3} \times base \times height$

The base of the pyramid would be:
(14.5÷4)^2
=3.625^2
=13.140625cm^2

We can then find the volume:
1/3x13.140625×16.8
=841/192×16.8
=73.5875
≈73.6cm^3

The answer is 73.6 cm^3.

Hope it helps!

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The correct option is A.

<h3>What is a triangle?</h3>

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.

The length of different sides are:

$AB = \sqrt{(5-1)^2+(-4-2)^2} = \sqrt{16+36} = \sqrt{52}\rm\ units$
