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

Answer 1

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.
