Answer 1

72 in squared

Explanation:

Answer 2

`V=22\ \text{inches}^3`

Explanation:

Given that,

Height of a triangular pyramid = 6 inches

The area of the base of the speaker is 11 square inches

We need to find the volume of the speaker.

The formula for the volume of triangular pyramid is given by :

`V=(1)/(3)Ah`

A is area of base and h is height

`V=(1)/(3)* 11* 6\\\\=22\ \text{inches}^3`

So, the volume of the speaker is
`22\ \text{inches}^3`.
