Use the formula for the surface area of a right rectangular prism to find the surface area of a shape with the following measurements: Length = 4.5 cm, width = 3.5 cm, and height = 2.5 cm.
35.75 cm^2
63 cm^2
71.5 cm^2
10.5 cm^2
1. 71.5 cm^2
2. 975.38 cm^2
3. 344 in.^2
4. Book A will require less wrapping paper because its surface area is 1.5 in.^2 less than the surface area of Book B.
5. 1,880 cm^2
ALL THE ANSWERS!! 🍪
have a great night. :3
The surface area of a right rectangular prism can be calculated using the formula:
Surface Area = 2lw + 2lh + 2wh
Substituting the given measurements:
Surface Area = 2(4.5)(3.5) + 2(4.5)(2.5) + 2(3.5)(2.5)
= 2(15.75) + 2(11.25) + 2(8.75)
= 31.5 + 22.5 + 17.5
= 71.5 cm^2
Therefore, the correct answer is option 3: 71.5 cm^2.
