Bella is wrapping a cube-shaped gift box that measures 8.5 inches along each edge. how many square inches of wrapping paper is needed to cover the box completely without overlapping?

we know that

The surface area of a cube is equal to

where

A is the area of one face of the cube

in this problem

Find the surface area

therefore

the answer is

 of wrapping paper is needed to cover the box completely

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
