I think your question missed key information, allow me to add in and hope it will fit the orginal one. Please have a look at the attached photo,
A solid oblique pyramid has an equilateral triangle as a base with an edge length of 4StartRoot 3 EndRoot cm and an area of 12StartRoot 3 EndRoot cm2.
What is the volume of the pyramid?
My
As we know, The volume of a pyramid = base area × its height
Given:
Side lenght of the base is;
=> The area of the base is
In Δ ACB measure of angle ACB is 90° and m∠ CAB is 30°
We use:
<=> BC =
= 4 cm
And BC is the height of the the pyramid
=> The volume of a pyramid = * 4 cm
=
