To calculate the surface area of a rectangular prism, we can use the formula 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.
For Book A:
Surface area = 2(6.5*1) + 2(6.5*8.5) + 2(1*8.5)
Surface area = 13 + 110.5 + 17
Surface area = 140.5 square inches
For Book B:
Surface area = 2(5.5*2) + 2(5.5*8) + 2(2*8)
Surface area = 22 + 88 + 32
Surface area = 142 square inches
Therefore, Book A will require less wrapping paper as it has a surface area of 140.5 square inches, while Book B has a surface area of 142 square inches.
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?

incorrect. way less than that
I apologize for the mistake in my previous calculation. Let's recalculate the surface area for both books:
For Book A:
Surface area = 2(6.5*1) + 2(6.5*8.5) + 2(1*8.5)
Surface area = 13 + 110.5 + 17
Surface area = 140.5 square inches
For Book B:
Surface area = 2(5.5*2) + 2(5.5*8) + 2(2*8)
Surface area = 22 + 88 + 32
Surface area = 142 square inches
Therefore, based on surface area, Book A requires less wrapping paper than Book B. Thank you for pointing out the error.

Therefore, based on surface area, Book A requires less wrapping paper than Book B. Thank you for pointing out the error.
no you don't get it let me rephrase and add the answers you can choose from
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?
Book A will require less wrapping paper because its surface area is 1.5 in.² less than the surface area of Book B.
Book A will require less wrapping paper because its surface area is 32.75 in.² less than the surface area of Book B.
Book B will require less wrapping paper because its surface area is 0.5 in.² less than the surface area of Book A.
Book B will require less wrapping paper because its surface area is 1.5 in.² less than the surface area of Book A.

give evidence
Surface area of Book A:
= 2(6.5 * 1) + 2(6.5 * 8.5) + 2(1 * 8.5)
= 2(6.5) + 2(55.25) + 2(8.5)
= 13 + 110.5 + 17
= 140.5 square inches
Surface area of Book B:
= 2(5.5 * 2) + 2(5.5 * 8) + 2(2 * 8)
= 2(11) + 2(44) + 2(16)
= 22 + 88 + 32
= 142 square inches
Now we compare the surface area of Book A to Book B:
Surface area of Book A = 140.5 square inches
Surface area of Book B = 142 square inches
Therefore, Book A will require less wrapping paper because its surface area is 1.5 in.² less than the surface area of Book B.
= 2(6.5 * 1) + 2(6.5 * 8.5) + 2(1 * 8.5)
= 2(6.5) + 2(55.25) + 2(8.5)
= 13 + 110.5 + 17
= 140.5 square inches
Surface area of Book B:
= 2(5.5 * 2) + 2(5.5 * 8) + 2(2 * 8)
= 2(11) + 2(44) + 2(16)
= 22 + 88 + 32
= 142 square inches
Now we compare the surface area of Book A to Book B:
Surface area of Book A = 140.5 square inches
Surface area of Book B = 142 square inches
Therefore, Book A will require less wrapping paper because its surface area is 1.5 in.² less than the surface area of Book B.
