Find the volume of 20m, 5m, 18m

HACTEHA [7]

Answer:

600 m³

Step-by-step explanation:

The shape we have is a rectangular pyramid:

Formula:<u><em> (volume of a rectangular pyramid)</em></u>

Volume = (1/3) × Base Area × height

___________________________

In our case :

Base area = L × W = 20 × 18 = 360 m²

height = 5 m

⇒ Volume = (1/3) × Base Area × height

$\Longrightarrow \text{volume} \ =\ \frac{1}{3} \times 360\times 5$

$\Longrightarrow \ \text{volume} \ =\ 600\ m^{3}$
