Find the volume of the pyramid shown.
Gnesinka [82]

Answer:

Volume of the shown pyramid is 40 square centimetre.

Step-by-step explanation:

Given:- From given figure we can see that,

Base length of the pyramid (L) = 5 cm.

Base width of the pyramid (W)= 4 cm.

Height of the pyramid (H)= 6 cm.

To find:- Volume of the pyramid = ?

Solution:-

Let, Base length of the pyramid be L,

Base width of the pyramid be W,

and height of the pyramid be H

Now,

Formula for volume of pyramid = \frac{Base\ length\times Base\ width\times Height\ of\ pyramid}{3}

Volume of pyramid = \frac{L\times W\times H}{3}

Volume of pyramid = \frac{5\times 4\times 6}{3}

Volume of pyramid = \frac{120}{3}

Volume of pyramid = 40 sq.cm.

Therefore volume of the shown pyramid is 40 square centimetre.
