The Drama Club Needs A plywood box with these dimensions: 70cm by 40cm by 50cm. A sheet of plywood has area 2.4m squared. How many sheets will be needed? (Please Answer Fast, Thank you :D)
Assuming all scraps are used, then you will need
240^2 / 2(70*40 + 70*50 + 40*50) = 3.46 sheets
So, buy 4 sheets
To find out how many sheets of plywood will be needed, we first need to determine the area of the plywood box.
The area of a rectangular box can be calculated by multiplying the length, width, and height. In this case, the length is 70cm, the width is 40cm, and the height is 50cm.
Area of the plywood box = Length × Width × Height
First, let's convert the dimensions to meters, as the area of the plywood is given in meters.
Length = 70cm ÷ 100 (since 1m = 100cm) = 0.7m
Width = 40cm ÷ 100 = 0.4m
Height = 50cm ÷ 100 = 0.5m
Now, we can calculate the area of the plywood box.
Area of the plywood box = 0.7m × 0.4m × 0.5m
Next, let's multiply the resulting dimensions:
Area of the plywood box = 0.14m²
Now we can determine how many sheets of plywood with an area of 2.4m² will be needed:
Number of sheets needed = Total area of the plywood box ÷ Area of one sheet of plywood
Number of sheets needed = 0.14m² ÷ 2.4m²
Finally, divide the total area of the plywood box by the area of one sheet of plywood:
Number of sheets needed = 0.06 sheets
Since you can't have a fraction of a sheet, you will need to round up to the nearest whole number.
Therefore, the Drama Club will need 1 sheet of plywood.
