Plz I Need Help The height of a square-based pyramid is 12cm. The volume of the pyramid is 676 cubic centimeters. How long is each side of the square base?
The side length of the square base is 14 cm.
What is the formula for a square-based pyramid in your Math Textbook? Just look it up!
V= [S^2 * H] / 3
676 =[S^2 * 12] / 3
Cross multiply
2028 =[S^2 * 12]
divide both sides by 12
169 =S^2
S = sqrt(169) =13 cm - side length of square base.
