Answer:
25
Explanation:
Each of the 5 pieces that goes into making a bowl is 1/2 ft square, so has an area of ...
A = s² = (1/2 ft)² = 1/4 ft²
Since there are 5 pieces required, the board area required for a bowl is ...
area for bowl = 5 × 1/4 ft² = 5/4 ft²
The 4 ft by 8 ft sheet of wood has an area of ...
A = LW = (8 ft)(4 ft) = 32 ft²
__
We can solve this proportion to find the number of bowls:
1 bowl/(5/4 ft²) = x bowls/(32 ft²)
Multiplying by 32 ft², we get ...
x bowls = (1 bowl)(32 ft²)/(5/4 ft²) = (4/5·32) bowls = 25.6 bowls
You can make 25 bowls from a 4 ft by 8 ft sheet of wood.
