Find the volume of a regular triangular pyramid if H = 12 and the side is the base 13.
September 29, 2021 | education
| To find the given volume, we calculate one third of the product of the height of the pyramid and the length of the side of the base squared:
V = 1/3 * 12 * 13 ^ 2 = 12/3 * 13 ^ 2.
Reduce the fraction in the expression by 3:
V = 4 * 13 ^ 2 = 4 * 169 = 676 (cm3).
Answer: the volume of a given regular pyramid is 676 (cm3).
