Could someone help me please?

600

Step-by-step explanation:

So lets rememer the formula for volume of a pyramid to sovle this:

LxHxW/3

Now lets plug in our values, for L, H, and W.

15x12x10/3

So, 15x12x10 is 1800. That is the height times the length times the width.

Now, since this isnt volume of a cube, we must divide the total my 3. This is how you find the volume of a pyramid, as I said above.

So it should be:

1800/3

=

600

This is your answer.

I hope this helps : )

Good luck!
