Question

На лесопилку привезли 10 одинаковых вагонов и 20 самосвалов с древесиной.Масса древисины на одном самосвале 40 ц 60 кг,а в одном вагоне - в 4 раза больше. Какова масса всей древесины?

Answer 1

40ц 60кг*20=800ц1200кг
40ц 60кг*4=160ц240кг
160ц 240кг*10=1600ц 2400кг
800ц1200кг+1600ц2400кг=2400ц3600кг

Answer 2

Calculation of the Total Mass of the Wood

To calculate the total mass of the wood, we need to consider the number of wagons and dump trucks, as well as the mass of wood in each dump truck and wagon.

Given information: - Number of wagons: 10 - Number of dump trucks: 20 - Mass of wood in one dump truck: 40 centners (c) + 60 kilograms (kg) - Mass of wood in one wagon: 4 times the mass of wood in one dump truck

Let's calculate the total mass of the wood step by step:

1. Calculate the 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)

2. Calculate the total mass of wood in all wagons: - Total mass of wood in all wagons: 10 * (4 * (40 c + 60 kg))

3. Calculate the total mass of wood in all dump trucks: - Total mass of wood in all dump trucks: 20 * (40 c + 60 kg)

4. Calculate the overall total mass of the wood: - Overall total mass of the wood: Total mass of wood in all wagons + Total mass of wood in all dump trucks

Let's perform the calculations:

1. Mass of wood in one wagon: - Mass of wood in one wagon = 4 * (40 c + 60 kg) = 4 * 40 c + 4 * 60 kg = 160 c + 240 kg

2. Total mass of wood in all wagons: - Total mass of wood in all wagons = 10 * (160 c + 240 kg) = 1600 c + 2400 kg

3. Total mass of wood in all dump trucks: - Total mass of wood in all dump trucks = 20 * (40 c + 60 kg) = 800 c + 1200 kg

4. Overall total mass of the wood: - Overall total mass of the wood = Total mass of wood in all wagons + Total mass of wood in all dump trucks - Overall total mass of the wood = (1600 c + 2400 kg) + (800 c + 1200 kg) = 2400 c + 3600 kg + 800 c + 1200 kg = 3200 c + 4800 kg

Therefore, the total mass of the wood is **3200 centners +
