In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle's centroid.

Can someone please help on this question

Answer:

The volume of the regular tetrahedron is 283.5 m³

Step-by-step explanation:

The formula of the volume of the regular tetrahedron is V = $\frac{1}{3}$ A h, where

A is the base area of it

h is the height of it

∵ The area of the base of a regular tetrahedron is 98.9 m²

∴ A = 98.9 m²

∵ The height of it is 8.6 m

∴ h = 8.6 m

→ Substitute them in the formula of the volume above

∵ V = $\frac{1}{3}$ (98.9)(8.6)

∴ V = 283.5133333 m³

→ Round it to the nearest tenth of a cubic meters

∴ V = 283.5 m³

∴ The volume of the regular tetrahedron is 283.5 m³
