Question

Площадь листа фанеры 354 см 2. Сначала отпилили треть этого листа, а потом еще половину оставшейся части. Сколько квадратных сантиметров листа фанеры после этого осталось?

Answer 1

1. 354/3 = 118 см2 - отпилили сначала
2. (354-118)/2 = 118 см2 - отпилили потом
3. 354-118-118 = 118 см2 - осталось.

Answer 2

354 разделить на 3 равно 118

Answer 3

Calculation of Remaining Plywood Sheet Area

To calculate the remaining area of the plywood sheet after removing one-third and then half of the remaining portion, we can follow these steps:

1. Start with the total area of the plywood sheet, which is given as 354 cm^2. 2. First, calculate one-third of the total area: 354 cm^2 * (1/3) = 118 cm^2. 3. Subtract this one-third portion from the total area to find the remaining area: 354 cm^2 - 118 cm^2 = 236 cm^2. 4. Next, calculate half of the remaining area: 236 cm^2 * (1/2) = 118 cm^2. 5. Subtract this half portion from the remaining area to find the final area: 236 cm^2 - 118 cm^2 = 118 cm^2.

Therefore, after removing one-third and then half of the remaining portion, there will be 118 square centimeters of plywood sheet remaining.
