Final answer:
The volume of a pyramid with a square base of side l and height h is given by the formula V = ⅓l²h. Calculate the area of the square base, then multiply by the height and divide by three.
Step-by-step explanation:
To find the volume of a pyramid with a square base of side l and a height of h, we can use the formula for the volume of a pyramid, which is one-third the base area multiplied by the height. This means we first need to calculate the area of the square base, which is l multiplied by l, or l². We then multiply this area by the height of the pyramid, and take one-third of that product to get the volume.
The formula can be expressed as V = ⅓l²h, where V is the volume of the pyramid, l is the length of a side of the square base, and h is the height of the pyramid.
