Sue is wrapping books to give as gifts book a has a length of 6.5 inches a width of 1 inch and a height of 8.5 inches book B has a length of 5.5 inches a width of 2 inches and a height of 8 inches based on surface area, which book will require less wrapping paper
To calculate the surface area of a rectangular prism, we use the formula:
Surface Area = 2(length * width) + 2(length * height) + 2(width * height)
For book A:
Surface Area of Book A = 2(6.5 * 1) + 2(6.5 * 8.5) + 2(1 * 8.5)
= 13 + 110.5 + 17
= 140.5 square inches
For book B:
Surface Area of Book B = 2(5.5 * 2) + 2(5.5 * 8) + 2(2 * 8)
= 22 + 88 + 32
= 142 square inches
Therefore, book A will require less wrapping paper as it has a surface area of 140.5 square inches, compared to book B with a surface area of 142 square inches.
