Question

На деревообробний комбінат завезли 10 однакових вагонів і 20 самоскидів деревини.Маса деревини на одному самоскиді 40 ц 60 кг, а в одному вагоні у 4 рази більша.Яка маса всієї деревини?

Answer 1

40 ц 60 кг = 4,06 т
4,06*4 = 16,24 т - древесины в одном вагоне.
16,24*10 = 162,4 т - во всех вагонах
4,06*20 = 81,2 т - во всех самосвалах.
162,4+81,2 = 243,6 т - всего древесины.

Answer 2

Calculation of the Total Mass of Wood

To calculate the total mass of wood, we need to determine the mass of wood in each wagon and each dump truck, and then sum them up.

Given information: - 10 identical wagons - 20 dump trucks - Mass of wood in one dump truck: 40 centners (c) + 60 kilograms (kg) - Mass of wood in one wagon is 4 times greater than in one dump truck

Let's calculate the mass of wood in one wagon first.

Mass of Wood in One Wagon

The mass of wood in one wagon is 4 times greater than in one dump truck. Since the mass of wood in one dump truck is 40 c + 60 kg, we can calculate the mass of wood in one wagon as follows:

Mass of wood in one wagon = 4 * (40 c + 60 kg)

Now, let's calculate the total mass of wood in all wagons.

Total Mass of Wood in Wagons

To find the total mass of wood in all wagons, we multiply the mass of wood in one wagon by the number of wagons:

Total mass of wood in wagons = Mass of wood in one wagon * Number of wagons

Now, let's calculate the total mass of wood in all dump trucks.

Total Mass of Wood in Dump Trucks

To find the total mass of wood in all dump trucks, we multiply the mass of wood in one dump truck by the number of dump trucks:

Total mass of wood in dump trucks = Mass of wood in one dump truck * Number of dump trucks

Finally, let's calculate the total mass of all the wood.

Total Mass of Wood

To find the total mass of all the wood, we sum up the total mass of wood in wagons and the total mass of wood in dump trucks:

Total mass of wood = Total mass of wood in wagons + Total mass of wood in dump trucks

Now, let's calculate the values.

Calculation

Mass of wood in one wagon: - Mass of wood in one dump truck = 40 c + 60 kg - Mass of wood in one wagon = 4 * (40 c + 60 kg)

Total mass of wood in wagons: - Total mass of wood in wagons = Mass of wood in one wagon * Number of wagons

Total mass of wood in dump trucks: - Total mass of wood in dump trucks = Mass of wood in one dump truck * Number of dump trucks

Total mass of wood: - Total mass of wood = Total mass of wood in wagons + Total mass of wood in dump trucks

Let's calculate the values.

Calculation Results

Mass of wood in one wagon: - Mass of wood in one dump truck = 40 c + 60 kg = 40 * 100 kg + 60 kg = 4060 kg - Mass of wood in one wagon = 4 * (40 c + 60 kg) = 4 * 4060 kg = 16240 kg

Total mass of wood in wagons: - Total mass of wood in wagons = Mass of wood in one wagon * Number of wagons = 16240 kg * 10 = 162400 kg

Total mass of wood in dump trucks: - Total mass of wood in dump trucks = Mass of wood in one dump truck * Number of dump trucks = 4060 kg * 20 = 81200 kg

Total mass of wood: - Total mass of wood = Total mass of wood in wagons + Total mass of wood in dump trucks = 162400 kg + 81200 kg = 243600 kg

Therefore, the total mass of all the wood is 243600 kilograms.
