Can someone please help, I need this done soon :))

A square pyramid has a height of 18 cm. A side length of the base of 11 cm. What is the volume of the pyramid?

________ cm3

Answer 1

The volume of the pyramid is
`$726 \mathrm\ {cm}^(3)$`

Step-by-step explanation:

The height of the square pyramid is 18 cm

The base of the square pyramid is 11 cm

The volume of the square pyramid can be determined using the formula,

`$V=(1)/(3) b^(2) h$`

Substituting
`b=11` and
`h=18` in the formula, we have,

`$V=(1)/(3) (11)^(2) (18)$`

Simplifying, we have,

`$V=(1)/(3) (121)(18)$`

Multiplying, we get,

`V=(2178)/(3)`

Dividing, we get,

`V=726 \ cm^3`

Thus, the volume of the pyramid is
`$726 \mathrm\ {cm}^(3)$`
