Find the volume $V$ of a pyramid if height $h = 20 cm$ and base area $B = 225 cm$ .

Answer

$1500 cm$

Explanation

STEP 1: find side $a$

To find side $a$ use formula:

After substituting $B = 225 cm$ we have:

B = a^{2}

a^{2} = 225 cm

a = 225 cm

a = 15

STEP 2: find volume $V$

To find volume $V$ use formula:

V = \frac{a ^{2} \cdot h}{3}

After substituting $a = 15 cm^{0}$ and $h = 20 cm$ we have:

V = \frac{225 \cdot 20 cm}{3}

V = \frac{4500 cm}{3}

V = 1500 cm
