First, we need to find the surface area of the three-ring binder.
There are two sides that measure 27.9 cm by 5.1 cm, giving us a total of 2(27.9 x 5.1) = 283.98 cm^2.
There are also two sides that measure 30.5 cm by 5.1 cm, giving us a total of 2(30.5 x 5.1) = 310.71 cm^2.
Finally, there is the base, which measures 28.4 cm by 5.1 cm, giving us 28.4 x 5.1 = 144.84 cm^2.
Adding these all together gives us a total surface area of 739.53 cm^2.
Since we need to cover both sides and the spine, we will need twice this amount of book cover material.
Therefore, we need approximately 1478 cm^2 of book cover material. Rounded to the nearest whole number, the answer is 1478.
A three-ring binder needs to be covered with enough book cover material. The binder measures 27.9 cm wide, 5.1 cm high, and 30.5 cm long, with the base being 28.4 cm. How much book cover material is needed to cover the three-ring binder? Round your answer to the nearest whole number.
Please answer this correctly and accurately.
