Question

Yolanda makes wooden boxes for a craft fair. She makes 150 boxes as the one shown, and she wants to paint all the outside faces.

L = 9in

W = 6in

H = 5in


Find the surface area of one box.





Find the surface area of one box.

Answer 1

`258 in^2`

Explanation:

Given the dimensions

L = 9 in

W = 6 in

H = 5 in

we can see that the craft is a cuboid/rectangular prism

the expression for the surface area is given as

`Surface -area=2lw+2lh+2hw`

substituting we have

`Surface- area=(2*9*6)+(2*9*5)+(2*5*6)`

`Surface -area=108+90+60= 258`

`Surface -area=258 in^2`
