Brass cast weight was 3.84 kg. It had turned into piston weight 3.491 kg. How many grams of brass were turned off? - Coke
One ton of coal is produced 772 kg of coke for iron production. How many wagons of coal by 13 tonnes per day is needed for the blast furnace, which has a daily consumption of 1020 tons of coke? - Brick weight
The brick weighs 4 kg and a half-brick. How much does one brick weigh? - Warehouses
To four warehouses is going cement in 25 kg bags, from first one third to the second quarter of the total. The third store got two-thirds of the rest, and the last 310 tons came to fourth. How much cement is in all warehouses, and how much got everyone? - Brick
The isosceles scale has all brick; the second weight is 1 kg and 1/4 of brick on one side. The balance is in equilibrium. What is the weight of a brick?
- Sea on the Moon
Assume that the Moon has a sea with the same composition as Earth's (it has the same density of saltwater). Calculate the boat's dive floating in the sea on the Moon when on Earth has dive 3.9 m. Consider that the Moon has 6.5-times smaller gravitational - Bricks
