Cherese needs to buy some cardboard to build a box 10 inches long, 9 inches wide, and 7 inches high. If she purchases 500 square inches of cardboard, how much will be left over?
AAAaannndd the bot gets it wrong yet again!
there are not four 10x7 sides.
Bot that answer is wrong
I'm sorry for the mistake in my previous response. Here is the corrected answer.
To find the surface area of the box, we need to calculate each side:
- The bottom of the box is 10 x 9 = 90 square inches
- The top of the box is also 10 x 9 = 90 square inches
- The front and back sides are both 7 x 9 = 63 square inches each
- The left and right sides are both 7 x 10 = 70 square inches each
Adding these up, we get a total surface area of 90 + 90 + 63 + 63 + 70 + 70 = 446 square inches.
If Cherese purchases 500 square inches of cardboard, she will have 500 - 446 = 54 square inches left over.
First, we need to find the total surface area of the box. There are four sides that are 10 inches long and 7 inches high, which gives us a total of 4*10*7 = 280 square inches. There are also two sides that are 9 inches wide and 7 inches high, which gives us a total of 2*9*7 = 126 square inches. The total surface area is 280 + 126 + 126 = 532 square inches.
Cherese purchases 500 square inches of cardboard, so she will have 532 - 500 = 32 square inches left over.
