The volume of a pyramid is given by:

Find the volume of the square pyramid:

V=BH B = 30^{2} = 900 cm^{2}

Using Pythagorean Pythagorean:

H^{2} = 17^{2} - 15^{2} = 289 - 225 = 64 H = 8 cm Therefore: V = ·900·8 = 2400 cm^{3}

V=48 cm^{3} H=8cm Find s

V=BH 48 = B · 8 3·6·= B·3 18 = B Let's look at the base:

72 = s^{2} 72 = s^{2} s = = s = 6
