Question

You are painting the outside of a jewelry box, including the bottom. To find the surface area (S.A.) of the jewelry box, you can use the formula S.A. = 2wl + 2lh + 2wh , where l is the length, w is the width, and h is the height. What is the surface area of the jewelry box in terms of x ?

Answer 1

1) The radius would be r = x + 4y 

.... and the area would be A = pi ( x + 4y )^2 

2) x is not defined. You have to state the relationship of x with l ,w, and, h 

3) The square prism is a cube. I assume that the edge is x. Then the perimeter of any one face is : 

... p = 4x
