Answer 1

1000 grams

is the answer.

Total volume of first metal block is 4 cm x 3 cm x 2.5 cm = 30 cub. cm

mass of each cub. cm of metal = 500 g/30 cub. cm

Total volume of new metal block = 5 cm x 4 cm x 3 cm = 60 cub. cm

mass of new metal block = (500g./30 cub.cm) x 60 cub. cm =1000 grams. or 1 kg

Answer 2

Answer:

Total volume of first metal block is 4 cm x 3 cm x 2.5 cm = 30 cub. cm

mass of each cub. cm of metal = 500 g/30 cub. cm

Total volume of new metal block = 5 cm x 4 cm x 3 cm = 60 cub. cm

mass of new metal block = (500g./30 cub.cm) x 60 cub. cm =1000 grams. or 1 kg
