the volume of the largest right circular cone that can be cut out of a cube of edge 7 cm is :
sol . volume of the block = ( 10 * 5 * 2 ) cm ³ . volume of the cone carved out = [ 1 / 3 * 22 / 7 * 3 * 3 * 7 ] cm ³ = 66 cm ³ ∴ wood wasted = ( 100 - 66 ) % = 34 % . answer a
divide(multiply(multiply(multiply(multiply(const_1, add(multiply(7, const_3), const_1)), divide(7, const_2)), divide(7, const_2)), 7), multiply(const_3, 7))
