Find the volume of the pyramid.

118.4

Step-by-step explanation:

So, lets go over what we know:

This is a pyramid.

The height is 8.

The width is 12.

The length is 3.7

We need to find the volume.

The formula for volume of a pyramid is:

Lets plug our values into this formula and solve:

Multiplying the numbers on top:

12*8 = 96

96*3.7=355.2

Now lets divide this by 3:

= 118.4

So this is your volume!

Hope this helps! :D

a28=58

step-by-step explanation:

a1=a1+(n-1)d
