as the question demands the brick to be 4 times smaller, it doesnt mean that all the parameters of the rectangle decrease 4 times.but it means the overall volume gets reduced by 4.so weight should be 4/4=1 kg

The question should have been the dimensions of the brick are 4 times smaller than the original dimensions....then the explanation given that it weighs 1/16th is valid
