Find the volume of a pyramid with a square base, where the side length of the base is 12.8 in and the height of the pyramid is 20.4 in. Round your answer to the nearest.
tenth of a cubic inch.

Volume = 1114.1

Step-by-step explanation:

Recall that the formula for the volume of a pyramid is given by:

where B is the area of the pyramid's base (in our case a square of side 12,8 in), and H the pyramid's height (in our case 20.4 in).

Then the square base of the pyramid has an area given by:

Finally,we can now write the volume of the pyramid as:

Rounding the answer to a tenth of a cubic inch, we get:

Volume = 1114.1

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
