Find the volume of the following square pyramid. geometry hw
Luda [366]

Given:

The square base pyramid with height 3 cm and base edge 2 cm.

To find:

The volume of the square pyramid.

Solution:

Volume of a square base pyramid is:

V=\dfrac{1}{3}Bh            ...(i)

Where, B is the base area and h is the height of the pyramid.

Base is a square with edge 2 cm, so the base area is:

B=a\times a

Where, a is the edge of the square base.

B=2\times 2

B=4

Putting B=4,h=3 in (i), we get

V=\dfrac{1}{3}(4)(3)

V=4

Therefore, the volume of the given pyramid is 4 cm³.
