Ewan is building a maze for his pet rats out of 2x4s. He needs two pieces that are 2 ¾ feet long, one that is 3.5 feet long and two that are 1 5/8 feet long. Ewan can buy wood that is 84 inches long at $2.35 per board, 96 inches long that costs $3.60 for each board, or a 10 foot board, for $4.61.

what's confusing? Just don't get lost in the maze of words!
He needs two pieces that are 2 ¾ feet long: 2*(2 3/4) = 5 1/2
one that is 3.5 feet long: 3 1/2
two that are 1 5/8 feet long: 2*(1 5/8) = 3 1/4
so, total wood is 5 1/2 + 3 1/2 + 3 1/4 = 12 1/4 feet = 147 inches
Ewan can buy wood that is 84 inches long at $2.35 per board, 96 inches long that costs $3.60 for each board, or a 10 foot board, for $4.61.
He needs (in inches) 33+33+42+19.5+19.5
Now split that up into various combinations of boards so he gets the lengths he needs.
Convert 0.96 to a fraction. The answer should be given in simplest form.
To find out how much total wood Ewan needs to build the maze, we can add up the lengths of all the individual pieces of wood.
Ewan needs:
- 2 pieces that are 2 ¾ feet long, which can be represented as 2.75 feet each.
- 1 piece that is 3.5 feet long.
- 2 pieces that are 1 5/8 feet long, which can be represented as 1.625 feet each.
To find the total wood needed, we add up all these lengths:
2.75 feet + 2.75 feet + 3.5 feet + 1.625 feet + 1.625 feet = 12.25 feet.
Thus, Ewan needs a total of 12.25 feet of wood to build the maze.
Please note that it is important to convert all lengths to the same unit (in this case, feet) before adding them together.
