Answer:
Step-by-step explanation:
Volume of a Prism=Base Area X Height
The base is an equilateral triangle of side 8cm.
We can find the area of the triangle using Herons Formula.
Given a triangle with sides a,b and c
Area
Where:
Semiperimeter, s
The sides are of length 8cm, 8cm and 8cm.
Therefore:
s
Area
Since Base Area =27.71cm^2
Volume=27.71*11.2
