Final answer:
You can cut 6 1 1/4' by 4' pieces from a 4' × 8' sheet of plywood.
Step-by-step explanation:
To find out how many 1 ¼' by 4' pieces can be cut from a 4' × 8' sheet of plywood, we need to divide the area of the plywood by the area of each piece.
The area of the plywood is 4' × 8' = 32 square feet.
The area of each piece is 1 ¼' × 4' = 5 square feet.
Therefore, the number of pieces that can be cut is 32 square feet / 5 square feet = 6.4 pieces. Since we cannot have a fraction of a piece, we round down to the nearest whole number.
So, you can cut 6 1 ¼' by 4' pieces from a 4' × 8' sheet of plywood.
