Gabriela will use of wood. Part B If she wants to include a top for the box, how much wood will Gabriela use?

Answer 1

In the problem we are given with the dimensions of the box as follows;

Length = `18 inch

Breadth = 15 inch

Height = 15 inch

Part A) When she wants to create a box with the open top

In this situation we will calculate the entire wood required apart from the the wood required for making the top

Therefore, Base = 18x15 , Side panels = 15x15, and 18x15

Total wood required = 18x15+2x(15x15)+2x(18x15)= 1260 inch²

Part B) Now we add the area of top to this area so we get

1260+18x15= 1530 inch²
