Station needs to buy some cardboard to build a box 10 in Long 9 in wide and 7 in high as she purchased 500 square inches of cardboard how much will be left over a 446 ft b 54 ft c 426 square inches deep 406 square inches
To calculate the total surface area of the box, we need to find the surface area of each side and then add them together.
- The front and back sides will each have an area of 10*7 = 70 square inches.
- The top and bottom sides will each have an area of 9*7 = 63 square inches.
- The two side walls will each have an area of 10*9 = 90 square inches.
Adding all the areas together, we get:
70 + 70 + 63 + 63 + 90 + 90 = 446 square inches.
Since Station purchased 500 square inches of cardboard, there will be 500 - 446 = 54 square inches left over.
Therefore, the correct answer is:
b) 54 square inches.
