Find the volume of a pyramid with a square base, where the perimeter of the base is 5\text{ in}5 in and the height of the pyramid is 3.6\text{ in}3.6 in. Round your answer to the nearest tenth of a cubic inch.

Volume = 1.9 in3

Step-by-step explanation:

If the perimeter of the square base is 5 inches, we have that:

Perimeter = 4 * side

5 = 4 * side

side = 1.25 in

Then, to find the volume of the pyramid, we can use the formula:

Volume = (1/3) * side^2 * height

So we have that:

Volume = (1/3) * 1.25^2 * 3.6

Volume = 1.875 in3

Rounding to nearest tenth, we have Volume = 1.9 in3

the answer will be b x² +x-1
