Best ResponseYou've already chosen the best response.1answer is 640 cm^3 how??? because solution: V= 1/2* l *w*h given V = 10 cm^3 but here given , new vol= 1/2* 4l*4w*4h =64 * 1/2* l*w*h =64*V =64*10 =640 cm^3

Best ResponseYou've already chosen the best response.1l*w*h = V if we use h= 2 w= 3 l= 4 V= 24 units^3 increase by 30% we get, h= 2.6 w= 3.9 l= 5.2 v =52.73 units^3 which is 219.7% time of the original volume original volume * 219.7% => 24 * 219.7% = 52.728 hence proved
