Question

The volume of the pyramid shown above is 147.97 units3 and the height is 9.6units. Find the length of one edge of the square base.

Answer 1

6.8 units

Explanation:

Formula for Area of a Pyramid:

V = 1/3 bh (b = area of triangular base)

147.97 = 1/3b(9.6)

Solve for b by dividing 147.97 by (1/3)(9.6)

b = 46.2

b is the area of the base so take the square root to find the length of one edge

√46.2 = 6.8 units
