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.

6.8 units

Step-by-step 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

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
