BRAINIEST ANSWER

:)) please help me out!

Step-by-step explanation:

Now the formula to find the volume of a pyramid is  

We know the length, width and height so let´s get started!

First let´s multiply to find the base. To do so, we will do length × width.

18 × 18 = 324

Now multiply by the height

324 × 12 = 3,888

After you multiply all length, width and height, we need to divide by three.

3,888 ÷ 3 = 1,296

Before we finish, we need to do the last two steps

First we need to add the measurement unit which is centimetres or cm.

We also need to add ³ since it is volume

1,296 cm³ is our final answer
