Lostulplastd A solid right circular cylinder of height 1.21 m and diameter 28 cm is melted and recast, hto 7 equal solid cubes. Find the edge of each cube.dug out to make a well 20 m deep and 2

Answer»

Volume of cylinder = pi*r*r*hGiven,r = 14 cm, h = 121 cm

Volume of cylinder Vcy = 22/7*14*14*121 = 74536 cm^3

Volume of cube Vcu = (edge) ^3

According to the given condition7*Vcu = Vcy7*(edge)^3 = 74536(edge)^3 = 10648Edge = 22 cm
