Question

a gift box with a width of 9in,height of 6in and a length of 8in is being wrapped at the store.how much paper is needed to cover the entire box?​

Answer 1

348

Basically there are 3 types of rectangles on a rectangular prism

Width by height

Width by length

Length by height

Find the areas of these 3 rectangles and multiply by 2. (Because there's 6 sides on a rectangular prism)

To find the areas, just plug in what you have

9(width) × 6(height) = 54

9(width) × 8(length) = 72

8(length) × 6(height) = 48

(54 + 72 + 48) = 174

174 × 2 = 348
