A whole block of modeling clay is a right rectangular prism six inches by two inches by one inch. How many whole blocks need to be unwrapped to mold a cylindrical sculpture seven inches high and four inches in diameter?
Volume of clay block = lxwxh =6x2x1= 12 in^3
Cylinder volume = pi r^2 h = pi (2)^2 7 = 87.965 in^3
87.965/12= 7.33 clay blocks ~ 8 clay blocks
