Rebecca designs a playing field for a new sport. The playing field is pitched. What is the area of the playing field

6 mm x 8 mm x 10 mm x 4 mm

To calculate the area of the playing field, you need to calculate the area of each rectangular face and add them together.

Area of face 1: 6 mm x 8 mm = 48 mm^2
Area of face 2: 6 mm x 10 mm = 60 mm^2
Area of face 3: 8 mm x 10 mm = 80 mm^2
Area of face 4: 6 mm x 10 mm = 60 mm^2

Total area of the playing field:
48 mm^2 + 60 mm^2 + 80 mm^2 + 60 mm^2 = 248 mm^2

Therefore, the area of the playing field is 248 mm^2.
