The volume of a pyramid is computed by multiplying the base length, base width, and pyramid height and divide it by 3. Volume = (base length x base width x height)/3 since this is a square, base length and width are equal. w=l=10cm h=12cm Substituting the given values in the formula, we will get the volume of the pyramid Volume=(10cmx10cmx12cm)/3 Volume= 400cm^3
