Answer:
The volume of the given pyramid is 300 cm³
Step-by-step explanation:
The volume of a pyramid,
, is given as follows;

The height of the pyramid = 12 cm
The side length of the square base of the pyramid = 5 cm
The base area of the pyramid polyhedron with square base = 5 cm × 5 cm = 25 cm²
Therefore, by substitution, we have;

The volume of the given pyramid, V = 300 cm³.
(x+12)^2 = 0
x + 12 = 0
x = - 12
Convert -6 1/8 to an improper fraction: -49/8
7(-49/8) = -343/8 = -42.875 = -42 7/8
Miranda is correct. 30×26=780 and 20×36=720 so 30×26>20×36
