The pyramid below has a square base.

zavuch27 [327]

The volume of the pyramid would be 2406.16 cubic cm.

<h3>How to find the volume of a square-based right pyramid?</h3>

Supposing that:

The length of the sides of the square base of the pyramid has = b units

The height of the considered square-based pyramid = h units,

The pyramid below has a square base.

h = 24.4 cm

b = 17.2 cm

Then, its volume is given by:

$V = \dfrac{1}{3} \times b^2 \times h \: \rm unit^3$

$V = \dfrac{1}{3} \times 17.2^2 \times 24.4 \: \rm unit^3\\\\V = 2406.16$

Therefore, the volume of the pyramid would be 2406.16 cubic cm.

Step-by-step explanation:

Here is one example:

$2\cdot \sin 0.5x \cdot \cos 0.5x$

$\sin 0.5x \cdot \cos 0.5x + \cos 0.5x\cdot \sin 0.5x$

$\sin (0.5x + 0.5x)$

$\sin x$
